Parameter

Description

pGraphicAnnSQItem

Pointer to an item element under the "Graphic Annotation Sequence" (0007,0001) in the "Graphic Annotation Module".

uImageIndex

Index of the image(SOP Instance).

Returns

!NULL

SUCCESS

NULL

An error occurred.

Comments

This function will return the "SOP Instance UID" for a referenced image (SOP Instance) under the "Referenced Image Sequence" (0008,1140) in one of the items under the "Graphic Annotation Sequence" (0007,0001) in the "Graphic Annotation Module". Use this function along with LDicomDS::GetLayerImageRefCount in order to enumerate all the referenced images under a certain "Graphic Annotation Sequence" item.
