[vtkusers]ask how to read DICOM(again)

[Shekhar Chandra]

Hi,

I dont think u want read the header manually. DICOM files are very 
vendor specific. Even major libraries have trouble reading various versions.

You could also look into GDCM library, which specifically contains a VTK 
based Reader class (like vtkPNGReader etc.). This might do what u want. 
It is easily built using cmake and is small (you dont need any library 
except VTK).

Cheers
Shekhar
