Content Item Descriptions

Row 2 “Perimeter Outline” The two dimensional perimeter of the volume’s intersection with or projection into the image. A Graphic Type of POINT implies that the volume’s intersection or projection in a plane is a single pixel. A single pixel projection perimeter cannot cause a volume calculation to become 0. Otherwise the type shall be a closed POLYLINE (start and end point the same) or a CIRCLE or an ELLIPSE.
Rows 5,6 Referenced Segment Number (0062,000B) is an attribute of the IMAGE Content Item. If the Referenced Segmentation SOP Instance has Segmentation Type (0062,0001) value BINARY, it identifies the defined (measured) volume by pixel/voxel values in the frames of the referenced segment with value 1. For Segmentation Type value FRACTIONAL, the volume is computed by an implementation dependent method. Segment number shall be specified even if the Segmentation SOP Instance has only a single segment.
