C.7.6.16.2.5.1 Use of Referenced Image Macro
Referenced Image Sequence (0008,1140) shall be used to identify other data objects used to plan the acquisition of this image. Instances referenced for this purpose shall have the same Frame of Reference UID (0020,0052) as this image. For each Item that contains such a reference, the value of Purpose of Reference Code Sequence (0040,A170) shall be (121311, DCM, "Localizer"). Applications can use the Referenced Image Sequence (0008,1140) in combination with data in Plane Position (Patient) and Plane Orientation (Patient) Macros to provide projections of the position of an image with respect to the referenced image.
The Referenced Image Sequence (0008,1140) may also be present when references to other images (or frames within other images) are required for other reasons, as specified by Purpose of Reference Code Sequence (0040,A170).
Note
An Image may contain references to itself (e.g., to other frames within itself).
