Get(DicomScp,DicomDataSet) Method

Summary
Sends a C-GET-REQ message to a peer member of a connection defined by Scp.
Syntax
C#
C++/CLI
public void Get( 
   DicomScp scp, 
   DicomDataSet request 
) 
public: 
void Get(  
   DicomScp^ scp, 
   DicomDataSet^ request 
)  

Parameters

scp
The peer connection to send the C-GET-REQ to

request
The DICOM data sets which describes the C-GET-REQ information to retrieve.

Remarks

The parameter  request should contain the QueryRetrieveLevel (0008,0052), which should be one of "STUDY", "SERIES", or "IMAGE".

  • If QueryRetrieveLevel is "STUDY", then  request should contain a valid StudyInstanceUID (0020,000D).
  • If QueryRetrieveLevel is "SERIES", then  request should also contain a valid SeriesInstanceUID (0020,000E).
  • If QueryRetrieveLevel is "IMAGE", then  request should also contain a valid SOPInstanceUID (0008,0018).
Example

This example does an image-level C-GET to retrieve an instance from a DICOM Server that supports C-GET Specifically, it retrieves one of the SMITH^TERRY instances that are in the LXX_SERVER32 database of the Leadtools.Dicom.Server.exe Replace XX with the version of the toolkit (i.e. for version 21, this would be L21_SERVER32) This overload takes a DicomDataSet that contains QueryRetrieveLevel, as well as the UIDs associated with the level Note that for this overload of Get, you must specifically add the SOP Class UID of the instance that you are retrieving to the Association
