A.51 Segmentation IOD​

A.51.1 Segmentation IOD Description​

The Segmentation Information Object Definition (IOD) specifies a multi-frame image representing a classification of pixels in one or​ more referenced images. Segmentations are either binary or fractional. If the referenced images have a defined Frame of Reference,​ the segmentation instance shall have the same Frame of Reference and is not required to have the same spatial sampling or extent​ as the referenced images. If the referenced image does not have a defined Frame of Reference, the segmentation instance shall​ have the same spatial sampling and extent as the referenced image.​

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

A.51.2 Segmentation IOD Entity-Relationship Model​

This IOD uses the E-R Model in Section A.1.2, with only the Image IE below the Series IE.​

A.51.5.1 Segmentation Functional Groups Description​

When a Frame of Reference UID is present the segment shall be specified within that coordinate system, using the Pixel Measures​ and either the Plane Position (Patient) and Plane Orientation (Patient), or the Plane Position (Slide) Functional Groups. Since this​ defines the spatial relationship of the segment, the size of the segmentation frames need not be the same size, or resolution, as the​ image data used to generate the segment data. The Derivation Image Functional Group may also be present, to specify on which​ images the segmentation was actually performed (since there may be others in the same Frame of Reference that are spatially co-​ located, but were not used to perform the segmentation).​

If the Frame of Reference UID is not present, each pixel of the segmentation shall correspond to a pixel in a referenced image, using​ the Derivation Image Functional Group. Hence, the rows and columns of each referenced image will match the segmentation image.​ If both the Frame of Reference UID and the Derivation Image Functional Group are present, the segmentation and referenced image​ pixels need not correspond.​

The value of Purpose of Reference Sequence (0040,A170) in the Derivation Image Functional Group Macro shall be (121322, DCM,​ "Source Image for Image Processing Operation"). The value of Derivation Code Sequence (0008,9215) shall be (113076, DCM,​ "Segmentation").​

Note​

Non-image source instances used during segmentation, such as real world value maps, can be described in the top level​ Data Set in the Source Instance Sequence (0042,0013) of the General Reference Module and are implied to have been​ used for the derivation of all frames. I.e., there is no mechanism for selectively specifying on a per-frame basis which non-​ image instances were used. Real World Value Map instances already contain a means of selectively applying different scale​ factors to different frames.​
