A.57 Surface Segmentation IOD

A.57.1 Surface Segmentation IOD Description

The Surface Segmentation 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.
