Visualizing a DICOM file of multiple frames

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',[]);

What does

size(image_data)

report ?

I suspect that what you are getting from dicomread() is an array of slices, and that you need to display one slice at a time,

imshow(image_data(:,:,1), [])

or else use

implay(image_data)

HI,

I read a DICOM pullback with the size 512x512x1x4235 .

I need to extract all the 4235 frames separately to find where the ROI started during acquisition.
