[vtkusers] Problems reading CT files from GE Hispeed NX

[Mathieu Malaterre]

Marcio,

   vtkDICOMImageReader only support a very limited subset of DICOM files. Could you check for instance that your images are not compressed ? If they are, you cannot use vtkDICOMImageReader.

Ps: For a more complete solution to read DICOM V3, ACR-NEMA and even Papyrus, check this link:
