SendInstances(DicomDataSet,String) Method

In This Topic

Sends an DataSet over a DicomAssociation with a defined abstract syntax.

Syntax

Visual Basic
C#

'Declaration
 
Public Overloads Sub SendInstances( _
   ByVal DataSet As DicomDataSet, _
   ByVal AbstractSyntax As System.String _

public void SendInstances(

   System.string AbstractSyntax
)

Parameters

DataSet: The DicomDataSet to send
AbstractSyntax: The abstract syntax to use

Remarks

The primary purpose of this overload is to send data where the asbtract syntax cannot be determined from the SOP class of the data being sent (e.g. when using meta-SOP classes), but it may also be useful when dealing with faulty remote entities.

For automatically generated DicomAssociation objects, this method is used in response to a C-GET or C-MOVE request, but it may also be used to send any images the client chooses over a "stand-alone" DicomAssociation.

Data sent by this method are sent either to the requesting application (C-GET) or to another (C-MOVE or stand-alone) as a series of C-STORE actions.

For C-MOVE operations, if this Association has been linked internally to the request (i.e. if it is the DicomObjects.EventArguments.QueryReceivedArgs.InstanceAssociation), then:

"pending" responses are generated automatically by this method.
The number of images remaining, failed, warning, and successful associated with the request are automatically updated by the method, and the Failures property maintains a list of refused images UIDs. If all images are to be returned via a single call to SendImages, then no specific client action is required, as NumberRemaining is set automatically to the number of images in Data if previously 0. If, however, the client wishes to return images via multiple calls to this method (e.g. to enable pending status messages), then NumberRemaining must be set correctly before the first image is returned.

For C-MOVE requests, or "stand-alone" DicomAssociation objects, Open must be called before this method.

Example

DicomDataSet PDFDicom = new DicomDataSet("pdf.dcm");
                    
string node = "dicomserver.co.uk";
int port = 104;
string callingAE = "SCU";
string calledAE = "SCP";
                    
using (DicomAssociation cn = new DicomAssociation())
{
    cn.RequestedContexts.Add(PDFDicom.SOPClass, TransferSyntaxes.ExplicitVRLittleEndian);
    cn.Open(node, port, callingAE, calledAE);
    cn.SendInstances(PDFDicom, SOPClasses.EncapsulatedPDF);
    
    var result = cn.LastStatus;
    
    cn.Close();
}
