I found the problem of sagittal deformation in CT head scanning

First of all, my English is not good, I'm very sorry.

I used Cornerstone3D in my project. At present, the sagittal images of chest CT scanning images and abdominal CT scanning images are OK. Most of the sagittal images of head CT scanning images are also OK. Some of the sagittal images of head CT scanning images are deformed. I used radiant reconstruction MPR, and the radiant display is correct. I don't know what the problem is with the sagittal images displayed here, Thank you.

The two screenshots are deformation and correct sagittal position respectively.

That is a CT with gantry tilt. I don't know if CS3D handles that data yet.

There's more information on this topic and how it is handled in Slicer here: https://slicer.readthedocs.io/en/latest/user_guide/modules/dicom.html#image-is-stretched-or-compressed-along-one-axis

Something similar may need to be added to CS3D.
