C.8.19.6 Enhanced XA/XRF Image Functional Group Macros

C.8.19.6 Enhanced XA/XRF Image Functional Group Macros (Current)
Prev	C.8.19 Enhanced XA/XRF Image	Next

The following sections contain Functional Group Macros specific to the Enhanced XA Image 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".".

C.8.19.6.1 X-Ray Frame Characteristics Macro

Table C.8.19.6-1 specifies the Attributes of the X-Ray Frame Characteristics Macro.

Table C.8.19.6-1. X-Ray Frame Characteristics Macro Attributes

Attribute Name	Tag	Type	Attribute Description
XA/XRF Frame Characteristics Sequence	(0018,9412)	1	A Sequence that describes general characteristics of this frame. Only a single Item shall be included in this Sequence.
>Derivation Description	(0008,2111)	3	A text description of how this frame was derived. See Section C.8.7.1.1.5 for further explanation.
>Derivation Code Sequence	(0008,9215)	3	A coded description of how this frame was derived. See Section C.12.4.1.1 for further explanation. One or more Items are permitted in this Sequence. More than one Item indicates that successive derivation steps have been applied.
>>Include Table 8.8-1 “Code Sequence Macro Attributes”			DCID 7203 “Image Derivation”.
>Acquisition Device Processing Description	(0018,1400)	3	Indicates any visual processing performed on the frame prior to exchange. See Section C.8.7.1.1.3.
>Acquisition Device Processing Code	(0018,1401)	3	Code representing the device-specific processing associated with the frame (e.g., Organ Filtering code) Note This Code is manufacturer specific but provides useful annotation information to the knowledgeable observer.
