How to render / display multiframe dicom images in vtk?

Question

I am using gdcm ImageReader to read multiframe dicom file. It reads multiframe correctly but I am unable to display the multiframe dicom file.

I am using vtkImageViewer to display single frame image,

  vtkImageViewer viewer = new vtkImageViewer();  
  vtkDICOMImageReader reader = new vtkDICOMImageReader();   
  reader.SetInputfile(..\\inputFile);  
  viewer.SetInput(reader.GetOutput());

It displays single frame images correctly but does not display multiframe images. Anybody knows how to display multiframe dicom files???

I would advise you to use vtkImageViewer2 instead of vtkImageViewer in this context. The former has a method, SetSlice, where, according to the documentation:

'Each call to SetSlice() changes the image data (slice) displayed AND changes the depth of the displayed slice in the 3D scene'

Example**:

vtkSmartPointer<vtkImageViewer2> imageViewer = vtkSmartPointer<vtkImageViewer2>::New(); imageViewer->SetSlice(5); //Specify the index/slice in image data

** Assumes you have set the input connection/data, example in c++ language.
