RetrieveImages Method

Summary

Starts the DICOM DataSets retrieval operation.

Syntax

C++

public IEnumerable<KeyValuePair<string, RetrievedDataSet>> RetrieveImages( 
   string studyInstanceUID, 
   string seriesInstanceUID 
)

  
Public Function RetrieveImages( _ 
   ByVal studyInstanceUID As String, _ 
   ByVal seriesInstanceUID As String _ 
) As IEnumerable(Of KeyValuePair(Of String,RetrievedDataSet))

public: 
IEnumerable<KeyValuePair<String^,RetrievedDataSet^>>^ RetrieveImages(  
   String^ studyInstanceUID, 
   String^ seriesInstanceUID 
)

Parameters

studyInstanceUID
The Study Instance UID System.String value against which to match the retrieved datasets. This can be null or System.String.Empty.

seriesInstanceUID
The Series Instance UID System.String value against which to match the retrieved datasets. This can be null or System.String.Empty.

Return Value

An System.Collections.IEnumerable of a KeyValuePair Enumerator which holds the DICOM instance SOP Instance UID as its key and a RetrievedDataSet as its value.

Remarks

The InstanceReceived event will be fired when each instance is received.

Calling this method while the Processing property is true results in an InvalidOperationException being thrown.

If the operation is cancelled this method throws a ClientCommunicationCanceled exception.
