Annex A Composite information object definitions(Normative)

A.1 ELEMENTS OF AN INFORMATION OBJECT DEFINITION

Each Composite Information Object Definition is composed of the following Sections

a. IOD Description

b. IOD Entity-Relationship Model

  1. IOD Module Table

  2. Optionally, a Functional Group Macros Table used by the Multi-frame Functional Groups Module

Sections A.1.1 through A.1.3 of this document define the requirements of a) through d) above.

A.1.1 IOD Description

This Section provides a brief description of the IOD. Specifically, this description includes:

⎯ The Real-World Object which is represented by the IOD

⎯ Information as to the scope of the represented object if appropriate

A.1.2 IOD Entity-Relationship Model

This Section of an IOD provides the Entity-Relationship (E-R) Model which depicts the relationships of the components or Information Entities (IE) of the specified IOD. It forms an IOD specific information model. This E-R model provides the complete context of how the composite instance information shall be interpreted when a composite instance is exchanged between two DICOM Application Entities.

Even though composite instances are sent as discrete individual components, each Composite Instance IOD E-R Model requires that all composite instances that are part of a specific study shall share the same context. That is, all composite instances within a specific patient study share the same patient and study information; all composite instances within the same series share the same series information; etc.

Figure A.1-1 is the DICOM Composite Instance IOD Information Model. It applies to all of the Composite Instance IODs defined in Annex A. However, a subset of this model may be specified by each individual Composite Instance IOD to accurately define the context for specific composite instance exchange.

Sections A.1.2.1 through A.1.2.10 describe the Information Entities (IE) which comprise the Composite Instance IODs defined in this Annex.

Figure A.1-1 DICOM COMPOSITE INSTANCE IOD INFORMATION MODEL

Each Series shall contain at least one Presentation State IE, SR Document IE or Image IE.

A.1.2.1 PATIENT IE

The Patient IE defines the characteristics of a patient who is the subject of one or more medical studies.

Note: A patient may be a human or an animal.

The Patient IE is modality independent.

A.1.2.2 STUDY IE

The Study IE defines the characteristics of a medical study performed on a patient. A study is a collection of one or more series of medical images, presentation states, and/or SR documents that are logically related for the purpose of diagnosing a patient. Each study is associated with exactly one patient.

A study may include composite instances that are created by a single modality, multiple modalities or by multiple devices of the same modality.

The Study IE is modality independent.

A.1.2.3 SERIES IE

The Series IE defines the Attributes that are used to group composite instances into distinct logical sets. Each series is associated with exactly one Study.

The following criteria group composite instances into a specific series:

a. All composite instances within a series must be of the same modality

b. If a specific Composite Instance IOD specifies the support of a Frame of Reference IE, all composite instances within the series shall be spatially or temporally related to each other; therefore, each series is associated with exactly one Frame of Reference IE

c. If a specific Composite Instance IOD specifies the support of the Equipment IE, all composite instances within the series shall be created by the same equipment; therefore, each series is associated with exactly one Equipment IE

d. All composite instances within a series shall have the same series information

Presentation States shall be grouped into Series without Images (i.e. in a different Series from the Series containing the Images to which they refer). The Frame of Reference IE is irrelevant to the Presentation State IE.

Note: The Series containing Grayscale, Color and Pseudo-Color Softcopy Presentation States and the Series containing the Images to which they refer are both contained within the same Study, except for Blended Presentation States, which may refer to images from different Studies.

Waveforms shall be grouped into Series without Images. A Frame of Reference IE may apply to both Waveform Series and Image Series.

SR Documents shall be grouped into Series without Images. The Frame of Reference IE does not apply to SR Document Series.

A.1.2.4 EQUIPMENT IE

The Equipment IE describes the particular device that produced the series of composite instances. A device may produce one or more series within a study. The Equipment IE does not describe the data acquisition or image creation Attributes used to generate the composite instances within a series. These Attributes are described in the composite instance specific IEs (e.g. the Image IE).

A.1.2.5 FRAME OF REFERENCE IE

The Frame of Reference IE identifies the coordinate system that conveys spatial and/or temporal information of composite instances in a series.

When present, a Frame of Reference IE may be related to one or more series. In this case, it provides the ability to spatially or temporally relate multiple series to each other. In such cases, the series may share the UID of the Frame of Reference, or alternatively, a Registration SOP Instance may specify the spatial relationship explicitly, as a spatial transformation. A Frame of Reference IE may also spatially register a Frame of Reference to an atlas.

A.1.2.6 IMAGE IE

The Image IE defines the Attributes that describe the pixel data of an image. The pixel data may be generated as a direct result of patient scanning (termed an Original Image) or the pixel data may be derived from the pixel data of one or more other images (termed a Derived Image). An image is defined by its image plane, pixel data characteristics, gray scale and/or color mapping characteristics, overlay planes and modality specific characteristics (acquisition parameters and image creation information).

An image is related to a single series within a single study.

The pixel data within an Image IE may be represented as a single frame of pixels or as multiple frames of pixel data. The frames of a Multi-frame image (a cine run or the slices of a volume) are sequentially ordered and share a number of common properties. A few Attributes may vary between frames (eg.-Time, Angular Displacement, Slice Increment). All common Image IE Attributes refer to the first frame of a multiple frame image.

Overlay and Lookup Table data may be included within an Image IE only if this information is directly associated with the image.

A.1.2.7 OVERLAY IE

The Overlay IE defines the Attributes that describe an independent set of Overlay Planes. The Overlay IE may represent in a bit-map format, graphics or text and is used to indicate such items as region of interest, reference marks and annotations. Sufficient information shall be available to allow an overlay to be presented at a display station superimposed on a particular image with which it is associated. An Overlay IE shall be related to only one Series IE.

An Overlay Plane may be represented as a single frame (when associated with a single frame image) or as multiple frames of overlay planes (when associated with a Multi-frame image).

A.1.2.8 CURVE IE

Retired. See PS 3.3 2004.

A.1.2.9 MODALITY LUT IE

The Modality LUT IE defines the Attributes that describe the transformation of manufacturer dependent pixel values into pixel values which are manufacturer independent (e.g. Hounsfield units for CT, Optical Density for film digitizers, etc.). The Modality LUT may be contained within an image, or a presentation state that references an image. When the transformation is linear, the Modality LUT is described by Rescale Slope (0028,1053) and Rescale Intercept (0028,1052). When the transformation is non-linear, the Modality LUT is described by Modality LUT Sequence (0028,3000).

A.1.2.10 VOI LUT IE

The VOI LUT IE defines the Attributes that describe the transformation of the modality pixel values into pixel values that are meaningful for print, display, etc. This transformation is applied after any Modality LUT. The VOI LUT may be contained within an image, or a presentation state that references an image. When the transformation is linear, the VOI LUT is described by the Window Center (0028,1050) and Window Width (0028,1051). When the transformation is non-linear, the VOI LUT is described by VOI LUT Sequence (0028,3010). A non-linear interpretation of Window Center (0028,1050) and Window Width (0028,1051) may be defined by VOI LUT Function (0028,1056).

A.1.2.11 PRESENTATION STATE IE

The Presentation State IE defines how a referenced image (or images) will be presented (e.g. displayed) in a device independent grayscale space (i.e. in P-Values) or color space (i.e. in PCS-values), and what graphical annotations and spatial and grayscale contrast transformations will be applied to the referenced image pixel data.

A.1.2.12 WAVEFORM IE

The Waveform IE represents a multi-channel time-based digitized waveform. The waveform consists of measurements of some physical qualities (e.g., electrical voltage, pressure, gas concentration, or sound), sampled at constant time intervals. The measured qualities may originate, for example, in any of the following sources:

a. the anatomy of the patient,

b. therapeutic equipment (e.g., a cardiac pacing signal or a radio frequency ablation signal),

c. equipment for diagnostic synchronization (e.g., a clock or timing signal used between distinct devices),

d. the physician’s voice (e.g., a dictated report).

The sample data within a Waveform IE may represent one or more acquired channels. Several signal channels acquired at the same sampling rate can be multiplexed (by interleaving samples) in a single multiplex group. (See also PS 3.17 Annex on Waveforms.)

A.1.2.13 SR DOCUMENT IE

The SR Document IE defines the Attributes that describe the content of an SR Document. These include semantic context as well as Attributes related to document completion, verification and other characteristics. An SR Document SOP Instance is related to a single Series within a single Study.

A.1.2.14 MR SPECTROSCOPY IE

The MR Spectroscopy IE defines the attributes that describe the data of a MR spectroscopy acquisition created by a magnetic resonance spectroscopy device.

A.1.2.15 RAW DATA IE

The Raw Data IE defines the attributes that describe a data set that may be used for further processing to produce image data or other data.

Note: For example, raw data may be used with CT and MR systems to reconstruct sets of images or for MR to reconstruct spectroscopic data. The format of the raw data is vendor specific.

A.1.2.16 ENCAPSULATED DOCUMENT IE

The Encapsulated Document IE defines the Attributes that describe the content of a non-DICOM formatted document that is encapsulated in a DICOM Attribute. These include Attributes related to document origin, title, and other characteristics. An Encapsulated Document SOP Instance is related to a single Series within a single Study.

A.1.2.17 REAL WORLD VALUE MAPPING IE

The Real World Value Mapping IE defines the attributes that describe the mapping of stored pixel data to real world values.

A.1.2.18 SURFACE IE

The Surface IE defines the Attributes that describe a surface in a spatial coordinate system. A surface is defined by its shape and can be further defined by normals on that shape. The surface may be reconstructed from either spatial scans (e.g. laser scanners) or based on images. A surface is described by its finite volume and manifold property, gray scale and color mapping characteristics, presentation type, opacity, and modality specific characteristics.

A surface is related to a single Series.

A.1.2.19 MEASUREMENTS IE

The Measurement IE defines the Attributes that describe the measurements taken by medical instruments.

A.8 Secondary capture image information object definition

The Secondary Capture (SC) Image Information Object Definition (IOD) specifies images that are converted from a non-DICOM format to a modality independent DICOM format.

Examples of types of equipment that create Secondary Capture Images include:

a. Video interfaces that convert an analog video signal into a digital image

b. Digital interfaces that are commonly used to transfer non-DICOM digital images from an imaging device to a laser printer

c. Film digitizers that convert an analog film image to digital data

d. Workstations that construct images that are sent out as a screen dump

e. Scanned documents and other bitmap images including hand-drawings

f. Synthesized images that are not modality-specific, such as cine-loops of 3D reconstructions

Originally, a single, relatively unconstrained, single-frame SC Image IOD was defined in the DICOM Standard. Though this IOD is retained and not retired since it is in common use, more specific IODs for particular categories of application are also defined.

The following IODs are all multi-frame. A single frame image is encoded as a multi-frame image with only one frame. The multi-frame SC IODs consist of:

- Multi-frame Single Bit Secondary Capture Image IOD

- Multi-frame Grayscale Byte Secondary Capture Image IOD

- Multi-frame Grayscale Word Secondary Capture Image IOD

- Multi-frame True Color Secondary Capture Image IOD

A.8.1 SC Image Information Objection Definition

A.8.1.1 SC Image IOD Description

The Secondary Capture (SC) Image Information Object Definition (IOD) specifies single-frame images that are converted from a non-DICOM format to a modality independent DICOM format, without any constraints on pixel data format.

A.14 X-Ray Angiographic Image Information Object Definition

A.14.1 XA Image IOD Description

This Section defines the Information Object for single plane X-Ray Angiographic Imaging that includes those data elements and information objects necessary for the interchange of digital X-Ray Angiographic data. This includes images of the heart and all blood vessels.

The XA IOD share a significant amount of common information with the XRF IOD. The differences between the two IODs are that the XRF Image IOD includes a tomography module; and the two IODs utilize different methods to specify positioner angles. The XRF Image IOD contains a single column angulation Data Element that uses an equipment based coordinate system, while XA Image IOD c-arm positioner angles are specified in a patient based coordinate system. RF applications that support a patient-based coordinate system with cranial/caudal, LAO/RAO angles may utilize the XA IOD.

The XA IOD is also applicable to clinical areas other than angiography (e.g. Interventional Procedures, Myelography, Biopsy/Localization, and Neurology).

Note: 1. For the purpose of X-Ray Angiography (XA), this IOD can be used to encode a single frame image, or a Cine Run encoded in a single multi-frame image.

2. A typical study might include all the images generated between the time a patient gets on and gets off the procedure table. As several separable diagnostic or therapeutic processes may occur during a single study (e.g., pre-intervention CA, left ventriculography, and post-intervention CA), a series may be defined as comprising a set of images (single or Multi-Frame) associated with one such process within a study.

3. This IOD can be used to encode a single plane acquisition, or one plane of a biplane acquisition.

A.14.2 XA Image IOD Entity-Relationship Model

The E-R Model in Section A.1.2 depicts those components of the DICOM Application Information Model that directly reference the X-Ray Angiographic Image IOD, with exception of the Frame of Reference and Modality LUT entities, which are not used. Additionally, "Image" in Figure A.1-1 may represent a Single Frame or a Multi-Frame image. A frame denotes a two-dimensional organization of pixels recorded as a single exposure.

A.15 X-Ray Angiographic Bi-Plane Image Information Object Definition (RETIRED)

A.16 X-RAY RF IMAGE INFORMATION OBJECT DEFINITION

A.16.1 XRF Image IOD Description

The focus for this X-Ray RF Image IOD (XRF IOD) is to address the requirements for image transfer found in general Radiofluoroscopic applications performed on a table with a column. For applications performed on X-Ray RF acquisition systems that support a patient based coordinate system with cranial/caudal, LAO/RAO angles, etc. the XA Image IOD may be used.

Note: An example of a case where the XA IOD may be preferred to the RF IOD are RF acquisition system equipped with an X-Ray source and an image Receptor positioned by what is generally called a c-arm (e.g. Interventional Procedures, Myelography, Biopsy, and Neurology).

This Section defines the Information Object for X-Ray Radiofluoroscopic Imaging that includes those data elements and information objects necessary for the interchange of digital X-Ray RF Image data. The XRF IOD is applicable to X-Ray acquisition systems equipped with an image receptor whose plane is parallel to the table plane where the patient is. This Table has in general the ability to be tilted. Furthermore the X-Ray source may be supported by a column that can be angulated to adjust the incidence of the X-Ray beam on the image receptor plan. An equipment based coordinated system is used to track these angles.

Notes: 1. For the purpose of X-Ray Radiofluoroscopy, this IOD can be used to encode a single frame image, or a cine run encoded in a single multi-frame image.

2. A typical study might include all the images generated between the time a patient gets on and gets off the procedure table. As several separable diagnostic or therapeutic processes may occur during a single study, a series may be defined as comprising a set of images (single or Multi-Frame) associated with one such process within a study.

A.16.2 XRF Image IOD Entity-Relationship Model

The E-R Model in Section A.1.2 depicts those components of the DICOM Application Information Model that directly reference the X-Ray RF Image IOD, with exception of the Frame of Reference entity that is not used. Additionally, "Image" in figure A.1-1 may represent a Single Frame or a Multi-Frame image. A frame denotes a two-dimensional organization of pixels recorded as a single exposure.

Note: When a Study (or Study Component) contains a number of Multi-frame images that do not need to be grouped under different Series, a single Series may be used with a series number containing an arbitrary value (e.g. 1).

A.17 RT Image INFORMATION OBJECT DEFINITION

A.17.1 RT Image IOD Description

The focus for this Radiotherapy Image IOD (RT Image IOD) is to address the requirements for image transfer found in general radiotherapy applications performed on conventional simulators, virtual simulators, and portal imaging devices. Such images have a conical imaging geometry and may either be acquired directly from the device, or digitized using a film digitizer. Numeric beam data parameters may also be recorded with the image, indicating the parameter values at the time the image was taken or created.

A.17.2 RT Image IOD entity-relationship model

The E-R model for the RT Image IOD is illustrated in Figure A.17-1.

Notes: 1. The inclusion of the Multi-Frame module allows for the expression of time-dependent image series or multiple exposures of identical beam geometries (i.e. multiple exposure portal images). If a time-dependent series of images (such as port images or DRRs) is represented the Cine module is used to indicate this. This would subsequently allow analysis of patient movement during treatment. Multiple exposure images allow individual images of treatment ports and open field ports to be grouped into a single multi-frame image.

2. The Modality LUT module has been included to allow the possibility of conversion between portal image pixel values and dose transmitted through the patient. The VOI LUT module has been included to allow the possibility of translation between stored pixel values (after the Modality LUT has been applied if specified) and display levels.

3. The Curve and Audio Modules were previously included in the Image IE for this IOD but has been retired. See PS 3.3 2004.

4. The Equipment module contains information describing the equipment used to acquire or generate the RT Image (such as a portal imager, conventional simulator or treatment planning system). However, the equipment attributes in the RT Image module describe the equipment on which the treatment has been or will be given, typically an electron accelerator.

5. For RT Images that contain no relevant pixel data, such as BEV images without DRR information, Pixel Data (7FE0,0010) should be filled with a sequence of zeros.

6. The Frame of Reference module has been included to allow the indication of spatial association of two or more RT Image instances (e.g. where the images have been acquired in the same frame of reference, or have been resampled to share the same frame of reference). If the Frame of Reference occurs within a SOP Instance within a given series, then all SOP Instances within that series will be spatially related. For example, two RT Images may share the same Frame of Reference if they are located on the same physical plane, as determined by the treatment machine Gantry Angle (300A,011E) and source to image plane distance specified by RT Image SID (3002,0026).

A.18 RT Dose Information Object Definition

A.18.1 RT Dose IOD Description

The focus for this Radiotherapy Dose IOD (RT Dose IOD) is to address the requirements for transfer of dose distributions calculated by radiotherapy treatment planning systems. These distributions may be represented as 2D or 3D grids, as isodose curves, or as named or unnamed dose points scattered throughout the volume. This IOD may also contain dose-volume histogram data, single or multi-frame overlays and application-defined lookup tables. This IOD does not provide for definition of doses in beam or other coordinate systems. The application is responsible for transforming data in other, non-patient based coordinate systems to the patient based coordinate system described in C.7.6.2.1.1.

A.18.2 RT Dose IOD entity-relationship model

The E-R model for the RT Dose IOD is illustrated in Figure A.18-1.

Notes: 1. Within the RT Dose IOD, the RT Dose module supports 2D and 3D dose grids. The Structure Set, ROI Contour and RT Dose ROI modules together support isodose curves and points, and the RT DVH module supports dose-volume histogram data. They are not mutually exclusive: all four representations may be included in a single instance of the object or they may be included in any combination. Product Conformance Statements should clearly state which of these mechanisms is supported and under what conditions.

2. The RT Dose IOD has been defined as a composite IOD, separate from the RT Plan IOD. This has been done for the following reasons:

- to allow for the multiplicity of possible dose calculations using beam models for the same basic plan,

- to avoid undesirable transmission of large amounts of data with the treatment plan, and

- to accommodate the fact that CT Simulation and other “beam geometry” generating devices that use the RT Plan IOD do not have or require access to this data, either for transmission or storage.

Notes: 1. The RT Structure Set referenced in Referenced Structure Set Sequence (300C,0060) of the RT General Plan Module may contain more than one item in the Referenced Frame of Reference Sequence (3006,0010) in the Structure Set Module. In this case, it is highly recommended that the Frame of Reference Module be supplied in the RT Plan object, to unambiguously specify the frame of reference of the RT Plan contents.

2. The Audio Module was previously included in this IOD but has been retired. See PS 3.3 2004.

A.20.3.1 RT FRACTION SCHEME MODULE

The RT Fraction Scheme module is structured to be used together with the RT Beams or RT Brachy Application Setups module. If beams are referenced in the RT Fraction Scheme module, all such beams shall be included in the RT Beams module if it is present. Similarly, if brachy application setups are referenced in the RT Fraction Scheme module, all such setups shall be included in the RT Brachy Application Setups module if it is present. However, the RT Fraction Scheme module can be used without the RT Beams or RT Brachy Application Setups modules if no beams or brachy application setups are referenced, and the RT Beams or RT Brachy Application Setups modules can also be used without the RT Fraction Scheme module if no fraction scheme information is available.

A.20.3.2 RT PRESCRIPTION MODULE

The RT Prescription module provides for the inclusion of dose prescription information pertinent to the complete plan, which may comprise several fraction schemes, themselves consisting of many beams.

A.20.3.3 RT TOLERANCE TABLES MODULE

The RT Tolerance Tables module provides information concerning machine tolerances as they apply to the whole treatment plan. Tolerances are applied by reference to a tolerance table within the RT Tolerance Tables module for beams contained within the RT Beams module.

A.20.3.4 RT PATIENT SETUP MODULE

The RT Patient Setup module provides information concerning patient setup parameters and fixation devices as they apply to the whole treatment plan. Patient setup information within the RT Patient Setup module is referenced by beams contained within the RT Beams module.

A.21 Positron Emission Tomography Image Information Object Definition

A.21.1 PET Image IOD Description

The Positron Emission Tomography (PET) Image Information Object Definition specifies an image that has been created by a Positron Tomograph imaging device, including dedicated PET cameras and Nuclear Medicine imaging devices operating in coincidence mode. This includes data created by external detection devices that create images of the distribution of administered radioactive materials, specifically positron emitters, in the body. Depending on the specific radiopharmaceuticals administered and the particular imaging procedure performed, problems involving changes in metabolism, function, or physiology can be investigated and various region pathologies can be studied. For these problems, quantitation of image data in absolute activity and physiological units is important. In addition, the PET Image IOD specifies attenuation (transmission) images used for correction and anatomical reference of emission images.

A.26 Digital X-Ray image information object definition

A.26.1 DX Image IOD Description

The Digital X-Ray (DX) Image Information Object Definition specifies an image that has been created by a digital projection radiography imaging device.

Notes: 1. This includes but is not limited to: chest radiography, linear and multi-directional tomography, orthopantomography and skeletal radiography. Acquisition of image data may include but is not limited to: CCD-based sensors, stimulable phosphor imaging plates, amorphous selenium, scintillation based amorphous silicon and secondary capture of film-based images.

2. Specific IODs are defined for intra-oral radiography and mammography that further specialize the DX IOD.

A DX image shall consist of the result of a single X-Ray exposure, in order to ensure that the anatomical and orientation attributes are meaningful for the image, permitting safe annotation, appropriate image processing and appropriate dissemination.

Notes: 1. This requirement specifically deprecates the common film/screen and Computed Radiography practice of making multiple exposures on different areas of a cassette or plate by using lead occlusion between exposures. Such acquisitions could be separated and transformed into multiple DX images during an appropriate quality assurance step by an operator.

2. This requirement does not deprecate the acquisition of multiple paired structures during a single exposure, provided that they can be described by the relevant orientation Attributes. For example, an AP or PA projection of both hands side by side is typically obtained in a single exposure, and can be described by a Patient Orientation (0020,0020) of R\H or L\H since both hands are in the same traditional Anatomical Position. See PS 3.17 annex on Explanation of Patient Orientation.

The DX Image IOD is used in two SOP Classes as defined in PS 3.4 Storage Service Class, a SOP Class for storage of images intended for presentation, and a SOP Class for storage of images intended for further processing before presentation. These are distinguished by their SOP Class UID and by the Enumerated Value of the mandatory Attribute in the DX Series Module, Presentation Intent Type (0008,0068).

Notes: 1. The Overlay Plane requirement is determined by the presence of “graphic annotation”. Graphic annotation includes user or machine drawn graphics or text (such as computer assisted diagnosis) to indicate regions of interest or descriptions. It specifically does not include patient or image identification or technique information that is defined in other Attributes of the IOD..

2. The Device and Intervention Modules are User optional, though it is desirable that, if present, they are stored by an SCP. It is recognized that in some cases the digital image acquisition system will not have a user interface or direct connection that allows acquisition of these parameters, even if device or therapy have been used.

3. The Frame of Reference, X-Ray Collimator, DX Positioning and DX Tomo Acquisition Modules are User optional, though it is desirable that, if present, they are stored by an SCP. It is recognized that in some cases the parameters of the mechanical devices used for collimation, positioning and tomography may not be available to a digital image acquisition system that is not integrated with the X-Ray generation and positioning system.

4. The Histogram Module may contain a single or multiple statistical representations of the pixel data used to derive the VOI LUT Module, or intended to be used to derive or replace the VOI LUT Module. The Histogram Module may contain statistics of a subset of the stored image pixel data (such as from a cropped area or region of interest that is not the full field of view) that are useful for deriving a better VOI LUT than might be derived from the statistics obtained from the entire stored pixel data.

5. The Specimen Identification Module was previously included in this IOD but has been retired, and its functionality replaced by the Specimen Module. See PS 3.3-2008.

6. The VOI LUT Module Attributes and behavior are further specialized in the DX Image Module.

7. The Curve Module was previously included in this IOD but has been retired. See PS 3.3 2004.

A.26.4 Overlay Plane Module

The value of Modality (0008,0060) shall be ES.

Note: The use of a single value for Modality recognizes the fact that the same acquisition equipment is often used for different purposes (e.g. laparoscopy and colonoscopy). This means that Modality is not useful to distinguish one type of endoscopy from another when browsing a collection of studies. Therefore, the use of Procedure Code Sequence (0008,1032) and Anatomic Region Sequence (0008,2218) in the image instances and in the query response is recommended, though gathering sufficient information to populate these attributes in an unscheduled workflow environment (i.e., in the absence of Modality Worklist) may require operator intervention.

Baseline Context ID for Purpose of Reference Code Sequence (0040,A170) is CID 8120.

A.32.8.4.1.2 Plane Position (Slide)

Frames shall occupy plane positions in a regular tiling of the Total Image Matrix; the frames may extend beyond the edges of the Total Image Matrix. Therefore, the value of Column Position In Total Pixel Matrix (0048,021E) shall be an integer multiple of the value of Columns (0028,0011) plus a constant, and the value of Row Position In Total Pixel Matrix (0048,021F) shall be an integer multiple of the value of Rows (0028,0010) plus a (possibly different) constant.

Note: Pixels beyond the edge of the Total Image Matrix may be encoded with a fixed padding value. For images with MONOCHROME2 Photometric Interpretation, see Pixel Padding Value (0028,0120) in Section C.7.5.1.1.2.

The encoding of tiles may be sparse; i.e., some tiles may not be encoded in frames. There are no constraints on the ordering of frames within the pixel data; each frame specifies its position in the Plane Position (Slide) Functional Group.

Note: Different SOP Instances within a Series may have different tiling boundaries and sizes.

Frames associated with different optical paths may coincide in any spatial dimension.

In the Grayscale Softcopy Presentation State IOD, the Presentation Series Module specializes some Attributes of the General Series Module, the Presentation State Mask Module specializes some Attributes of the Mask Module, and the Presentation State Shutter Module specializes some Attributes of the Bitmap Display Shutter and Display Shutter Modules.

Notes: 1. Subtraction between different images is not supported.

2. The Mask Module condition implies that it need not be supported by an SCP that supports presentation states only for single frame image storage SOP Classes, or instances of multi-frame image Storage SOP Classes that contain only one frame.

3. The Display Shutter may be used to darken image areas that surround important information and exclude extraneous bright areas that increase glare and ambient lighting impairing image interpretation. For example, unexposed areas in a CR image might be obscured using the Display Shutter, rather than permanently replacing image pixels in those areas.

4. This IOD does not support the storage of a multi-frame overlay in the IOD itself, but does support selective activation of multi-frame overlays within the referenced images via the Overlay Activation Module.

A.36 ENHANCED mr information object definitionS

A.36.1 Relationship between Enhanced MR IODs

Figure A.36-1 illustrates the relationships between the Enhanced MR IODs described in Section A.36.

Source Image Sequence (0008,2112), Referenced Image Sequence (0008,1140) and Referenced Raw Data Sequence (0008,9121) provide references between SOP Instances.

Note: Many attributes have names and descriptions that include the terms “pixel” and “image”. Although MR spectroscopy is not pixel based, some of these “pixel” and “image” attributes encode concepts that are still relevant for this technique. Where such attributes appear in the MR Spectroscopy IOD, it may be helpful to consider the term “pixel” to be equivalent to a spectroscopy “voxel”, and the term “image” to be equivalent to “MR Spectroscopy SOP Instance”.

A.39.2 Deformable Spatial Registration information object definition

A.39.2.1 Deformable Spatial Registration IOD Description

The Deformable Spatial Registration Information Object Definition (IOD) describes spatial relationships between images in one or more frames of reference via deformation grids and transformation matrices. The deformations and transformations describe to an application how to sample data from one or more Source RCSs into the Registered RCS.

The Registered RCS is the Frame of Reference specified within an instance of this IOD. The IOD may specify that only a subset of the entire Source RCS Frame of Reference is affected by the transformation, by specifying specific frames of image SOP Instances that use the Source Frame of Reference.

The deformation is described as a grid of offset vectors. Each grid element contains 3 values representing offset distances in the X, Y, and Z directions at the center position of the deformation grid element. The relationship between the data being deformed and the deformation grid is purely spatial. Therefore the resolution of the grid is independent of the data being deformed.

A.39.2.2 Deformable Spatial Registration IOD Entity-Relationship Model

The E-R Model for the Deformable Spatial Registration IOD is identical to the E-R Model for the Spatial Registration IOD in Figure A.39-1.

A.47 ENHANCED X-Ray Angiographic Image Information Object Definition

A.47.1 Enhanced XA Image IOD Description

This Section defines the enhanced Information Object for single plane X-Ray Angiographic Imaging that includes those data elements and information objects necessary for the interchange of digital X-Ray Angiographic data. This includes images of the heart and all blood vessels.

The enhanced XA IOD is also applicable to clinical areas other than angiography (e.g. Interventional Procedures, Myelography, Biopsy/Localization, and Neurology).

Notes: 1. For the purpose of X-Ray Angiography (XA), this enhanced IOD can be used to encode a single frame image, or a Cine Run, or a single multi-frame image with non-time related dimensions.

2. A typical study might include all the images generated between the time a patient gets on and gets off the procedure table. As several separable diagnostic or therapeutic processes may occur during a single study (e.g., pre-intervention CA, left ventriculography, and post-intervention CA), a series may be defined as comprising a set of images (single or Multi-Frame) associated with one such process within a study.

3. This enhanced IOD can be used to encode a single plane acquisition, or one plane of a biplane acquisition.

A.47.2 Enhanced XA Image IOD Entity-Relationship Model

The E-R Model in Section A.1.2 depicts those components of the DICOM Application Information Model that directly reference the enhanced X-Ray Angiographic Image IOD. Additionally, “Image” in Figure A.1-1 may represent a Single Frame or a Multi-Frame image. A frame denotes a two-dimensional organization of pixels recorded as a single exposure.

A.57 Surface Segmentation information object definition

A.57.1 Surface Segmentation IOD Description

The Surface Segmentation Information Object Definition (IOD) specifies a polygonal representation of a three dimensional surface. A Surface Segmentation SOP Instance may reference an externally defined coordinate system via the Frame of Reference UID (0020,0052) or establish its own coordinate system.

The Surface Segmentation IOD does not include the full set of acquisition parameters of the referenced images, e.g. cardiac phase. An application rendering or processing the segmentation may need to access the referenced images for such information.

One Segmented Surface Instance can contain one or more surfaces. Each surface within a Segmented Surface IE is represented as a single object.

A.57.2 Surface Segmentation IOD Entity-Relationship Model

The E-R Model in Section A.1.2 depicts those components of the DICOM Information Model that directly reference the Surface Segmentation IOD. The Surface Segmentation uses a polygonal surface mesh representation to define the contained surfaces.

A.59 Enhanced Ultrasound Volume Information Object Definition

A.59.1 Enhanced US Volume IOD Description

Image objects of different types may be created from a 3D Ultrasound image acquisition, illustrated in Figure A.59-1. It can be seen that there are two different types of data related to 3D image acquisition: 3D volume datasets and several kinds of 2D image derived from the volume dataset.

[pic]

Figure A.59-1: Types of 3D Ultrasound Source and Derived Images (Informative)

The 3D volume dataset (the diagonally shaded box in Figure A.59-1) contains a Cartesian volume or two or more temporally related Cartesian volumes. 3D volume datasets are exchanged using the Enhanced US Volume SOP Class, and are suitable for subsequent Multi-Planar Reconstruction and rendering operations. Within each Enhanced US Volume instance, each Cartesian volume consists of a set of parallel planes, and each plane consists of one or more frames each of a single data type. All Cartesian volumes have the same spacing between adjacent planes.

Most acquisition devices construct the Cartesian volume by resampling data from a different acquisition geometry. The method of generation of the Cartesian volume, its relationship to spatially-related 2D frames (whether the volume was created from spatially-related frames, or spatially-related frames extracted from the Cartesian volume), and the algorithms used for Multi-Planar Reconstruction and rendering operations are outside the scope of this standard.

The 2D image types represent collections of frames that are derived from the volume dataset, namely 3D rendered views (projections), separate Multi-Planar Reconstructed (MPR) views, or sets of spatially-related source frames, either parallel or oblique (the cross-hatched boxes in Figure A.59-1). The Ultrasound Image and Ultrasound Multiframe Image IOD’s are used to represent these derived images. See Section A.6 for the Ultrasound Image IOD description or section A.7 for the Ultrasound Multi-frame Image IOD description.

Note: See PS3.17 “3D Ultrasound Volumes” for an informative discussion on the use of these objects for the exchange of 3D ultrasound volume data.

A.59.3.1 Enhanced US Volume IOD Content Constraints

A.59.3.1.1 Associated Physiological Waveforms

The Acquisition Time Synchronized attribute (0018,1800) shall have a value of ‘Y’ if associated physiological waveforms are linked to the Enhanced US Volume. As described in the Synchronization Module, the same value of the Synchronization Frame of Reference UID (0020,0200) is shared between the Waveform and Enhanced US instances to indicate a common temporal frame of reference for the Acquisition Datetime (0008,002A) values in the waveform and Enhanced US instances. Further, the Frame Reference Datetime attribute (0018,9151) may be used in optimizing alignment between the displayed image and displayed physiological waveforms.

In the case of gated acquisition in which information from multiple events (such as ECG beats) are used to create sub-volumes that are “spliced” or “interleaved” together to form the volume dataset, the Excluded Intervals Module describes the timing of each of the constituent sub-volumes for correlation with the physio waveform.

Note: It is recommended that the Waveform Annotation Module in the General ECG Waveform IOD be used to indicate the times of the R-wave events within the acquisition duration. This allows the viewing application to be able to mark those R-R intervals that contributed to the acquisition of the Enhanced US Volume.

A.66 Intravascular OCT Information Object Definition

This Section defines an Information Object to be used with Intravascular Optical Coherence Tomography imaging devices.

A.66.1 Intravascular OCT Image IOD Description

The Intravascular Optical Coherence Tomography Image IOD specifies a multi-frame image acquired on an Intravascular Optical Coherence Tomography modality.

The Intravascular OCT Image IOD is used in two SOP Classes as defined in PS 3.4 Storage Service Class, a SOP Class for storage of images intended for presentation, and a SOP Class for storage of images intended for further processing before presentation. These are distinguished by their SOP Class UID and by the Enumerated Value of the mandatory Attribute in the Intravascular OCT Series Module, Presentation Intent Type (0008,0068).

IVOCT stores frames of polar data arranged in a rectangular format when “FOR PROCESSING” is specified. The A-lines in a frame are arranged in row order, with the catheter optics toward the left of the image. A-lines are always stored from top to bottom, in order of acquisition. The A-lines are evenly spaced (in angles) to form a complete 360 degrees of acquisition.

Application entities creating IVOCT FOR PRESENTATION SOP instances shall apply all needed processing (e.g., Z offset and refractive index correction) to the IVOCT image for correct presentation.

A.66.2 Intravascular OCT Image IOD Entity-Relationship Model
