Get(DicomScp,string,List<PresentationContext>) Method

Summary

Sends a STUDY-level C-GET-REQ message to a peer member of a connection defined by Scp.

Syntax

C++

public void Get( 
   DicomScp Scp, 
   string StudyInstanceUID, 
   List<PresentationContext> additionalPresentationContexts 
)

  
Public Overloads Sub Get( _ 
   ByVal Scp As DicomScp, _ 
   ByVal StudyInstanceUID As String, _ 
   ByVal additionalPresentationContexts As List(Of PresentationContext) _ 
)

public: 
void Get(  
   DicomScp^ Scp, 
   String^ StudyInstanceUID, 
   List<PresentationContext^>^ additionalPresentationContexts 
)

Parameters

Scp
The peer connection to send the C-GET-REQ to.

StudyInstanceUID
The study instance UID of the study to retrieve.

additionalPresentationContexts
A list of presentation contexts to add to the Leadtools.Dicom.DicomAssociate

Remarks

This method uses a C-GET to retrieve a complete study. Note that the C-GET differs from the C-MOVE in that the C-GET requests and retrieves information on the same DICOM assocation. This means that you need to know the SOP Class UID of the DICOM instances that are to be retrieved prior to the DICOM assocation. You can add these additional SOP Classes to the association by using the additionalPresentationContexts parameter. The example shows how this is done.

Example

This example retrieves instances from a DICOM Server that supports C-GET Specifically, it retrieves the five SMITH^TERRY instances that are in the LXX_SERVER32 database of the CSLeadtools.Dicom.Server.exe Replace XX with the version of the toolkit (i.e. for version 19, this would be L19_SERVER32) There are four overloads for Get This examples illustrates how to use three of the overloads (study level, series level, instance level) Uncomment any of the overloads in the example to see how it is used
