Hi all, I tried to develop cerebral arteries using DSA dicom having multiple slices of axial view. I patched the files using dicom patcher module. And then imported as Dicom data. But the sagittal and coronal views developed looks somewhat skewed. Then I tried to apply threshold to the region of in…

It looks like you have variable slice spacing and need to enable acquisition geometry regularization option. These links should help. [image] Understanding CT Image spacing and Acquisition geometry regularization Support Dear all, "Images are not equally spa…

Hi, I enabled the acquisition geometry regularization option in Edit>Application Settings> Dicom. After that I restarted Slicer App. But the results were the same. Also I couldn’t find the Dicom plugin option in slicer version 4.11.20210226 I am new to Slicer 3d. Thanks Manjunath [Screenshot…

Hi, I tried resampling data. And made the the image dimensions 1024, 1024,1028 by changing the image spacing from 1mm,1mm, 1mm to 1mm, 1mm, 0.5mm. But the problem still persists, when I develop the 3d volume the cross section of vessels are still rectangular [Screenshot 2022-03-04 154103]

It sounds like these files have been modified in some way because it’s rare that data that comes directly from any medical scanner would have this kind of issues. I suggest tracing back to wherever you got them to see if you can get originals.
