I am facing the same problem. If the settings during configuration of ITK in CMake is are left at default, the coordinates differ a lot. If ITK_IMAGE_BEHAVES_AS_ORIENTED_IMAGE is set to false, then coordinates match (but then the patient orientation is lost).<div>
<br></div><div>And by coordinates, I mean the ones received from calls to TransformIndexToPhysicalPoint, TransformPhysicalPointToContinuousIndex and companions.<br><br></div><div>To obtain vtkImage I am using ImageToVTKImageFilter. Any help on this?</div>

Hello anyone,<br>
<br>
I wonder how I can adjust ITK coordination to VTK coordination.<br>
I got information from CT images and applied some algorithms to CT data<br>
using ITK.<br>
Using ITK functions, I could handle each pixels of the CT image (e.g., 512 x<br>
512 pixel image).<br>
And then I visualized the result using VTK. Also I visualized CT images<br>
using VTK directly.<br>
However, even I used same CT images, but the ITK result and VTK result were<br>
different according to coordination.<br>
<br>
So, what I'm asking is how I can transform ITK coordinate to VTK's one.<br>
I tried to search this issues but I cannot find informative article.<br>
Is there an mathematical relationship between ITK and VTK, or any function?<br>
Please answer how to calculate or how to use functions for coordination.<br>
<br>
Thank you very much.<br>
<br>
Best regards,<br>
LEE<br>
