[vtkusers] VTK+MFC displaying DICOM image

[Kiran Gachchi]

Hi All,

I want to read a DICOM slice using VTK and display it using MFC.
I wrote the following code for the same.  It should display gray scale image. But I am getting RGB color DICOM image.

   vtkRenderer           *pvtkRenderer;
   vtkDataSetMapper      *pvtkDataSetMapper;
   vtkActor             *pvtkActor;
   vtkDICOMImageReader   *pvtkDICOMImageReader;


   pvtkDICOMImageReader->SetFileName(DicomFileName);
  pvtkDataSetMapper->SetInputConnection(pvtkDICOMImageReader->GetOutputPort());
   pvtkActor->SetMapper(pvtkDataSetMapper);
   pvtkRenderer->AddActor(pvtkActor);
  pvtkRenderer->ResetCamera();
   pvtkRenderer->GetRenderWindow()->Render();
   pvtkRenderer->ResetCamera();

Please help me out.

Thanks in Advance.

Regards,
Kiran
