Summary0004409: CT images acquired with gantry tilt are loaded incorrectly
Description

CT images acquired with gantry tilt are loaded incorrectly, probably the gantry tilt information is ignored. The image appears to be warped.

See for example this discussion:
https://discourse.slicer.org/t/how-to-adjust-the-distorted-image/817

Workaround: use a tool that can convert gantry-tilted DICOM to rectified image files. For example: dicomtonifti tool. Download from here: https://github.com/dgobbi/vtk-dicom/releases

Potential implementation: use vtkDICOM classes.

Target is 4.9, then if it is stable enough, it could be backported to the 4.8 maintenance branch.
