[vtkusers] Problems with vtkDICOMImageReader

[Paulo Henrique Junqueira Amorim]

Hello all,

I am using the class vtkDICOMImageReader (VTK 5.1.0) to read several dicom
files acquired with different CT equipments. It worked fine for more than
200 cases.

However, recently, I had trouble reading dicom files acquired with Toshiba
Aquilion. The image returned by the vtkDICOMImageReader is noisy (full of
grayscale dots), pretty similar to fft output. Does anyone know how to solve
this?

I'm attaching one of the files acquired with Toshiba Aquilion so other
developers can reproduce the problem.

The source code that illustrates the pipeline can be seen below.

Thanks in advance,

Paulo Amorim

from vtk import *

reader = vtkDICOMImageReader()
reader.SetFileName('D:\\dcm_file')

viewer = vtkImageViewer()
viewer.SetInput(reader.GetOutput())
viewer.SetColorWindow(400)
viewer.SetColorLevel(0)
viewer.Render()
