C.8.21.1 X-Ray 3D Image Module

This section describes the X-Ray 3D Image Module. Table C.8.21.1-1 contains IOD Attributes that describe a X-Ray 3D Image by specializing Attributes of the General Image and Image Pixel Modules, and adding additional Attributes.

Table C.8.21.1-1X-Ray 3D IMAGE MODULE ATTRIBUTES

Attribute Name Tag Type Attribute Description
Image Type (0008,0008) 1 Image identification characteristics. See C.8.21.1.1.1 for specialization.
Include ‘Common CT/MR Image Description Macro’ Table C.8-131
Bits Allocated (0028,0100) 1 Number of bits allocated for each voxel sample. Each sample shall have the same number of bits allocated. Enumerated Values: 8 and 16.
Bits Stored (0028,0101) 1 Number of bits stored for each voxel sample. Each sample shall have the same number of bits stored. Enumerated Values: 8 to16.
High Bit (0028,0102) 1 Most significant bit for pixel sample data. Each sample shall have the same high bit. Shall be one less than the value in Bits Stored (0028,0101).
Samples per Pixel (0028,0002) 1 Number of samples (color planes) in this image shall have a value of 1.
Photometric Interpretation (0028,0004) 1 Specifies the intended interpretation of the voxel data. Enumerated Values: MONOCHROME2
Content Qualification (0018,9004) 1 Content Qualification Indicator Enumerated Values: PRODUCT RESEARCH SERVICE See C.8.13.2.1.1 for further explanation.
Burned In Annotation (0028,0301) 1 Indicates whether or not the image contains sufficient burned in annotation to identify the patient and date the image was acquired. Enumerated Values: NO
Recognizable Visual Features (0028,0302) 3 Indicates whether or not the image contains sufficiently recognizable visual features to allow the image or a reconstruction from a set of images to identify the patient. Enumerated Values: YES NO If this Attribute is absent, then the image may or may not contain recognizable visual features.
Lossy Image Compression (0028,2110) 1 Specifies whether an Image has undergone lossy compression. Enumerated Values: 00 = Image has NOT been subjected to lossy compression. 01 = Image has been subjected to lossy compression. See C.7.6.1.1.5 for further explanation.
Lossy Image Compression Ratio (0028,2112) 1C See C.7.6.1.1.5 for further explanation. Required if Lossy Image Compression (0028,2110) equals 01.
Lossy Image Compression Method (0028,2114) 1C A label for the lossy compression method(s) that have been applied to this image. See C.7.6.1.1.5 for further explanation. May be multi-valued if successive lossy compression steps have been applied; the value order shall correspond to the values of Lossy Image Compression Ratio (0028,2112). Note: For historical reasons, the lossy compression method may also be described in Derivation Description (0008,2111). Required if Lossy Image Compression (0028,2110) equals 01.
Referenced Image Evidence Sequence (0008,9092) 1C Full set of Composite SOP Instances referred to inside the Referenced Image Sequences of this SOP Instance. See C.8.13.2.1.2 for further explanation. One or more Items shall be included in this sequence. Required if the Referenced Image Sequence (0008,1140) is present.
>Include ‘Hierarchical SOP Instance Reference Macro’ Table C.17-3
Image Comments (0020,4000) 3 User-defined comments about the image.
Quality Control Image (0028,0300) 3 Indicates whether or not this image is a quality control or phantom image. Enumerated Values: YES NO If this Attribute is absent, then the image may or may not be a quality control or phantom image.
Icon Image Sequence (0088,0200) 3 This icon image is representative of the Image. Only a single Item is permitted in this sequence.
>Include ‘Image Pixel Macro’ Table C.7-11b See C.7.6.1.1.6 for further explanation.
Presentation LUT Shape (2050,0020) 1 Specifies a predefined identity transformation for the Presentation LUT such that the output of all grayscale transformations, if any, are defined to be in P-Values. Enumerated Values: IDENTITY = output is in P-Values
