C.8.21.5 X-Ray 3D Image Functional Group Macros

The following sections contain Functional Group Macros specific to the X-Ray 3D IOD.


The Attribute descriptions in the Functional Group Macros are written as if they were applicable to a single frame (i.e., the Macro is part of the Per-frame Functional Groups Sequence). If an Attribute is applicable to all frames (i.e., the Macro is part of the Shared Functional Groups Sequence) the phrase "this frame" in the Attribute description shall be interpreted to mean " for all frames".".

C. X-Ray 3D Frame Type Macro

Table C. specifies the Attributes of the X-Ray 3D Frame Type Functional Group Macro.

Attribute Description

X-Ray 3D Frame Type Sequence



A Sequence that describes general characteristics of this frame.

Only a single Item shall be included in this Sequence.

>Frame Type



Type of Frame. A multi-valued Attribute analogous to Image Type (0008,0008).

Enumerated Values and Defined Terms are the same as those for the four values of Image Type (0008,0008), except that the value MIXED is not allowed. See Section C. For Breast Tomosynthesis Image See Section C.

>Reconstruction Index



The Item number of the X-Ray 3D Reconstruction Sequence (0018,9530) that describes the characteristics of the 3D Reconstruction to which this frame is part of.

Required if the X-Ray 3D Reconstruction Sequence (0018,9530) is present.
