GetPresentationStateImageReferenceCount Method (original) (raw)
Summary
Retrieves number of images (SOP Instances) that are referenced in an item under the "Referenced Series Sequence" (0008,1115) in the "Presentation State Module".
Syntax
public int getPresentationStateImageReferenceCount(DicomElement refSeriesSQItem) Parameters
refSeriesSQItem
An item element under the "Referenced Series Sequence" (0008,1115) in the "Presentation State Module".
Return Value
The number of referenced images.
