[vtkusers] rendering dicom file

[audi2006 at pop.singnet.com.sg]

Hi!
Have anybody been successful rendering dicom file??
I tried to render dicom file after I convert it to raw data, but I only 
manage to render the outline of the data.I used vtkVolume16Reader.
But I don't know how to make the image smooth or like the original 
image.

What is the difference between vtkVolume16Reader and vtkImageReader??

Hope somebody can help me...I really stuck here.

Thanks a lot,
Semmala
