Non-standard geometry

[effepivi]

Changes

Testing you performed

I tested the functionality using:

• Data simulated with gVXR of a traditional circular CT acquisition but converted in per-projection geometry;
• Real data of a traditional circular CT acquisition but converted in per-projection geometry;
• Data simulated with gVXR of a non-standard CT acquisition geometry; and
• Real data of a non-standard CT acquisition geometry with a detector tilting constantly on 2 axes during the scan.
