FindDisplayedCellInstanceInformation(MedicalViewerMultiCell,int) Method

Summary
Finds the instance information for the image displayed in the specified cell.
Syntax
C#
C++/CLI
public DicomInstanceInformation FindDisplayedCellInstanceInformation( 
   MedicalViewerMultiCell cell, 
   int subCellIndex 
) 
public: 
DicomInstanceInformation^ FindDisplayedCellInstanceInformation(  
   MedicalViewerMultiCell^ cell, 
   int subCellIndex 
)  

Parameters

cell
The Leadtools.MedicalViewer.MedicalViewerMultiCell object in which the image is displayed.

subCellIndex
The index for the sub cell containing the image.

Return Value

A DicomInstanceInformation that contains the information for the displayed image in the specified Leadtools.MedicalViewer.MedicalViewerMultiCell and sub cell index.

Remarks

Create the  cell by calling the LoadSeries(String,String) method of this MedicalViewerLoaderBase object to find the related instance information.
