Description

The attached modification of d01_standard_geometries.py demonstrated that if the number of detector rows is set so the detector z-span is less than the scaled recon volume, the slices outside the detected FOV are repeats of the last valid slice, but should be zero

Research direction

Start by reproducing the reported behavior with the attached d01_standard_geometries_bug.py modification, then trace how detector rows and the scaled reconstruction volume determine z-slices. Done means slices outside the detected field of view contain zeros rather than repeats of the last valid slice; no specific test is named in the issue.
