[vtkusers] how to read dicom file using python?

[RimAY]

Hi all,
I'm trying to read a Dicom file using python. I have successfully built
VTK_5.2.1 in python 2.4, but I failed to use vtkDICOMImageReader(). I got
many errors .

Please, can someone give me the right method to use in order to read a Dicom
file using vtk and python.
Thanks a lot
Best Regards

Do you really expect anyone to help you out without:
1. Sending the actual error
2. Sending the actual code you were using

I'm sorry,
Thanks for your reply,

Here is my code:

import vtk

reader = vtk.vtkDICOMImageReader()
reader.SetDirectoryName('the root of my dicom files')
win = 400000
lev = 400000

viewer = vtk.vtkImageViewer()
viewer.SetInputConnection( reader.GetOutputPort() )
viewer.SetColorWindow(win)
viewer.SetColorLevel(lev)
viewer.Render()

viewer2 = vtk.vtkImageViewer2()
viewer2.SetInputConnection( reader.GetOutputPort() )
viewer2.SetColorWindow(win)
viewer2.SetColorLevel(lev)
viewer2.Render()

iren = vtk.vtkRenderWindowInteractor()
viewer2.SetupInteractor(iren)
iren.Initialize()

and I got the following error:: vtkDICOMImageReader[015579F0]: Couldn't get
stored files.

Please could someone help me to resolve it
Thanks a lot

Did you mean 'sorted' ?

Implicitely vtkDICOMImageReader will only works with MR Image Storage
or CT Image Storage, as it requires Image Orientation (Patient) and
Image Position (Patient) attribute to order slices.

You could use vtkGDCMImageReader as it does not have such restriction.
