How to find that attachment is at study level or series level?

Hi,

We have an application of dicomviewer where we play dicom studies.Some studies have audio or pdf attachments.Those attachments may be at series level or study level.How can i find that particular attachment is at study level or at series level?Is there any DicomTag to know that?Please let me know ASAP

Thanks

At instance/IMAGE level query response, you may get values in SOP Class UID tag (0008, 0016) from a SCP, and this should have a value such as "1.2.840.10008.5.1.4.1.1.104.1" for Encapsulated PDF Storage object or "1.2.840.10008.5.1.4.1.1.9.4.2" for General Audio Waveform Storage.

You can also use the value in the Modality Tag (0008, 0060) at SERIES level query response from PACS. As for example value "AU" will mean the object type is Audio data and "DOC" or "SR" to represent Encapsulated PDF/CDA (see PS .3.3 section C.7.3.1.1.1 for Defined Terms).

LEADTOOLS also offers ways to insert and extract PDF from DICOM dataset (GetEncapsulatedDocument and SetEncapsulatedDocument Methods) and refer to "Working with DICOM Waveforms" section of the help file.
