Table C.188.8.131.52-1US IMAGE DESCRIPTION MACRO ATTRIBUTES
|Attribute Name||Tag||Type||Attribute Description|
|US Image Description Sequence||(0018,9806)||1||A sequence that describes a general description of this image or frame. Only a single Item shall be included in this sequence.|
|>Frame Type||(0008,9007)||1||Type of Frame. A multi-valued attribute analogous to the Image Type (0008,0008). Enumerated Values and Defined Terms are the same as those for the four values of the Image Type (0008,0008) attribute, except that the value MIXED is not allowed. See section C.184.108.40.206.|
|>Volumetric Properties||(0008,9206)||1||Indication if geometric manipulations are possible with frames in the SOP Instance. See C.220.127.116.11.2 for a description and Enumerated Values.|
|>Volume Based Calculation Technique||(0008,9207)||1||Method used for volume calculations with frames in the SOP Instance. See C.18.104.22.168.3 for a description and Defined Terms.|
If Volumetric Properties (0008,9206) is VOLUME and Volume Based Calculation Technique (0008,9207) is NONE, all frames in the frame set shall be spaced the same Z-distance from adjacent frames (i.e., spacing between slices is constant).
