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

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

Syntax

C#
Visual Basic
Objective-C
Java
C++

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

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

'Usage
 
Dim instance As QueryRetrieveScu
Dim Scp As DicomScp
Dim StudyInstanceUID As String
Dim additionalPresentationContexts As List(Of PresentationContext)
 
instance.Get(Scp, StudyInstanceUID, additionalPresentationContexts)

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.
