Hello,
Astra offers a 2D-FBP algorithm for parallel beam data, however, FBP is not supported for the 'parallel3d' nor 'parallel3d_vec' geometry.
The documentation has a page "https://www.astra-…

Hi. There appears to be a bug in astra's fan-beam projection code. I have included image examples and source code to produce a particularly potent example.

I need to create a 2D fan beam geometry with a radius equal of the distance of the centre detector.
The detectors on the array, are equally x degrees spaced from each other.
As I understand from the…
