#include "l_bitmap.h"

L_CHAR* EXT_FUNCTION L_DicomGetPresStateImageRefSOPInstance(hDS, pRefSeriesSQItem, uImageIndex)

HDICOMDS hDS;	/* a DICOM handle */
pDICOMELEMENT pRefSeriesSQItem;	/* pointer to a DICOMELEMENT structure */
L_UINT uImageIndex;	/* index of the required image */

Returns the SOP Instance UID for a referenced image (SOP Instance) under the "Referenced Image Sequence" in the "Presentation State Module".

Parameter	Description
hDS	A DICOM handle.
pRefSeriesSQItem	Pointer to an item element under the "Referenced Series Sequence" (0008,1115) in the "Presentation State 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" (0008,1115) in one of the items under "Referenced Series Sequence" (0008,1115) in the "Presentation State Module". Use this function along with L_DicomGetPresStateImageRefCount in order to enumerate all the referenced images under the specified "Referenced Image Sequence".
