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 interest and the resulted 3d model is having square and rectangular cross section instead of circular or oval.
Operating system: Windows 10
Expected behavior: Cerebral arteries with oval or circular cross section
Actual behavior: Cerebral arteries in the developed 3d models shows rectangular or square shapes
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.
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.
