Visualizing a DICOM file of multiple frames in Matlab

Question

I generated this brain tumor via TumorSim and converted it from .mha to .dcm using the gdcm2vtk tool.

https://www.dropbox.com/s/70gwje0a8pb42tf/T1Gad.dcm

I want to visualize it now in Matlab 2012a, I tried this, following the ankle demo (which is based on a single frame dicom file):

 info = dicominfo('T1Gad.dcm');
   image_data = dicomread('T1Gad.dcm');

   imtool(image_data,'DisplayRange',[]);

I get the following errors:

 Error using imageDisplayValidateParams>validateCData (line 117)
  Unsupported dimension.

  Error in imageDisplayValidateParams (line 31)
  common_args.CData = validateCData(common_args.CData,image_type);

  Error in imtool/addImageToImtool (line 323)
         common_args = imageDisplayValidateParams(common_args);

  Error in imtool (line 270)
            addImageToImtool(varargin{:});

  Error in mostrarDicom (line 12)
  imtool(image_data,'DisplayRange',[]);

First, info is a poor choice of name because it overwrites matlab's info. Second, and to the point, image_data is a 4-D matrix. To see a slice you can try:

n=40 ; %slice number
imshow(image_data(:,:,n), [])
