Hi Matias,<br>
<br>
When the vtkDICOMImageReader reads an image, it reads the bottom<br>
row of the image first. That might be the cause of the difference that<br>
you are seeing.<br>
<br>
As far as I'm aware, all of the VTK image readers store the images<br>
bottom-to-top in the data array. They do it this way in order to be<br>
consistent with each other, and to be consistent with VTK's display<br>
coordinate system.<br>
