Value 3 is an overall representation of the image type. This value may be a summary of several other attributes or a duplication of one of the other attributes to indicate the most important aspect of this image. Value 3 Image Flavor is to be used with Value 4 Derived Pixel Contrast to indicate the nature of the image set.
Note: For example Value 3 = DIFFUSION together with Value 4 = NONE indicates that the image set was originally collected for DIFFUSION.
If Value 3 = DIFFUSION together with Value 4 = DIFFUSION this indicates that the object contains DIFFUSION weighted post processed images.
Value 3 of Image Type (0008,0008) shall not be zero length.
Value 3 of Frame Type (0008,9007) may have the same value as found in Value 3 of Image Type (0008,0008), or may have a different value or may be of zero length.
The attribute value may not be MIXED as this value needs to be a summary of the primary purpose of the images, whether the frames have the same value or not.
Table C.8-129 specifies the Defined Terms for Value 3 for Image Type (0008,0008) and Frame Type (0008,9007) that are common to CT and MR. Additional defined terms are defined in the modality-specific Module and Macro definitions.
Table C.8-129IMAGE TYPE AND FRAME TYPE VALUE 3 COMMON
|Defined Term Name||Defined Term Description|
|ANGIO||Collected for the purpose of angiography|
|CARDIAC||Images of the heart|
|CARDIAC_GATED||Cardiac gated images, other than of the heart|
|CARDRESP_GATED||Cardiac and respiratory gated images|
|DYNAMIC||An image in which the same anatomical volume is imaged at multiple times in order to capture images of a non-cyclic, time varying event. For example, imaging of the uptake of a tracer or contrast in a specific organ over time. Note: This is different from gating techniques, in which the same anatomical volume is imaged during some portion of a cyclic event , e.g. inspiration or R-R Interval.|
|FLUOROSCOPY||Real-time collection of single slices (e.g. CT or MR Fluoroscopy)|
|LOCALIZER||Collected for the purpose of planning other images.|
|MOTION||Collected for looking at body motion|
|PERFUSION||Collected for the purposes of perfusion calculations.|
|PRE_CONTRAST||Collected before contrast was administered|
|POST_CONTRAST||Collected during or after contrast was administered|
|RESP_GATED||Respiratory gated images|
|REST||Cardiac rest image set|
|STATIC||A group of frames at varying spatial locations acquired at the same time.|
|STRESS||Cardiac stress image set|
|VOLUME||Set of frames that define a regularly sampled volume|
|NON_PARALLEL||Set of frames that are not parallel|
|PARALLEL||Set of frames that are parallel but do not constitute a regularly sampled volume|
|WHOLE_BODY||A group of frames of the whole body; the frames may be acquired at various times (as distinct from STATIC).|
