LoadSeries(string,string,IMedicalViewerCellFactory) Method

Summary
Loads a series of images and related information into a Leadtools.MedicalViewer.MedicalViewerMultiCell controls.
Syntax
C#
C++/CLI
public bool LoadSeries( 
   string studyInstanceUID, 
   string seriesInstanceUID, 
   IMedicalViewerCellFactory cellFactory 
) 
public: 
bool LoadSeries(  
   String^ studyInstanceUID, 
   String^ seriesInstanceUID, 
   IMedicalViewerCellFactory^ cellFactory 
)  

Parameters

studyInstanceUID
A System.String representing the Study Instance UID.

seriesInstanceUID
A System.String representing the Series Instance UID.

cellFactory
A IMedicalViewerCellFactory representing the medical cell.

Return Value

True if the series is loaded; otherwise it is false.

Remarks

The series of images will be displayed in Leadtools.MedicalViewer.MedicalViewerMultiCell controls with their overlay tag information.

If the ViewerControl is set before calling this method, A Leadtools.MedicalViewer.MedicalViewerMultiCell will be created and added to that MedicalViewer control which will raise the ViewerCellCreated event.

If the value of the ViewerControl is null (Nothing in VB) the MedicalViewerCellRequested event will be raised and the user is responsible for handling the event and providing the Leadtools.MedicalViewer.MedicalViewerMultiCell control. If the MedicalViewerCellRequested event is not handled an exception will be thrown and the method will fail.

A series will be sorted and depending on the DICOM information of the series may be separated among multiple cells. The images with the same Frame Of Reference, Echo Number and Image Orientation will be grouped together. This will ensure the DICOM images in the Leadtools.MedicalViewer.MedicalViewerMultiCell are displayed properly.
