#### 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.

### Note

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".".
