How to independently modify the curvature radius of the curved detector?

[ImJ00]

Hello, and thank you for providing such an excellent toolbox.
I am currently working on curved detector research, and I found that very few toolboxes support applying FBP to curved detectors. Among them, LEAP seems to be the best option, so I installed it and went through the technical manual.

From what I understand, LEAP supports curved detector geometry, but the curvature radius of the detector appears to be automatically fixed to the SDD (source-to-detector distance). Could you confirm if this understanding is correct?

If so, it would be extremely helpful if LEAP could allow a curved detector with a curvature radius that is independently defined, separate from the SDD.

Thank you very much.

Best regards,

Your understanding is correct and unfortunately, there is no way to change the curvature in LEAP.

You could try to re-interpolate the data so that the curvature does match LEAP's convention. LEAP has built-in rebinning functions for this. See d09_curved_polygon_detector_array.py for an example.
