Summary
Retrieves the item element, which represents a referenced image (SOP Instance) under the "Referenced Image Sequence" in the "Presentation State Module".
Syntax
C#
C++/CLI
Java
public DicomElement GetPresentationStateImageReference( 
   string sopInstanceUID 
) 
public DicomElement getPresentationStateImageReference(String sopInstanceUID) 
public: 
DicomElement^ GetPresentationStateImageReference(  
   String^ sopInstanceUID 
)  

Parameters

sopInstanceUID
Character string that contains the SOP Instance UID of the image whose item element will be retrieved.

Return Value

Item element which represents a referenced image (SOP Instance) under the "Referenced Image Sequence" in the "Presentation State Module".

Remarks

This method will return the item element, which represents a referenced image (SOP Instance) under the "Referenced Image Sequence" in the "Presentation State Module". A null reference (Nothing in VB) will be returned if the item could not be found.

Example
C#

      dicomDataset.AddPresentationStateImageReference(Path.Combine(LEAD_VARS.ImagesDir, "DICOM", "IMAGE3.dcm"), null, 0); 
 
      // We can also add the presentation state using a stream

      DicomElement item = dicomDataset.FindFirstPresentationStateReferencedSeriesItem(); 
 
      string imageRefSOPInstanceUID = dicomDataset.GetPresentationStateImageReferenceSOPInstance(item, 0); 
      Debug.Assert(imageRefSOPInstanceUID != null); 
      DicomElement item1 = dicomDataset.GetPresentationStateImageReference(imageRefSOPInstanceUID); 
      Debug.Assert(item1 != null); 
 
      dicomDataset.Save(Path.Combine(LEAD_VARS.ImagesDir, "DICOM", "PresentationState.dcm"), DicomDataSetSaveFlags.None); 
   } 
   DicomEngine.Shutdown();
