ASTRA scaling factor change in next release

7

Hi, A quick heads-up: in the next ASTRA release the scaling factor of the ASTRA BP code ODL uses has been changed by a factor `reco_space.cell_volume ** 2` (since commit...

Add bindings to ASTRA cylindrical detector geometries

1

This adds bindings for the `CylindricalDetector` geometry to the astra_cuda tomography backend. Known bug: there is a misinterpretion of the detector center if the detector partition isn't centered around 0,...

Use more accurate adjoint weighting for 2D geometries in ASTRA

1

## Description Astra 2.3 (Feb 2025) added a mode for using a more accurate weighting for the adjoint when using the Astra 3D projectors for a 2D geometry. This PR...

## Description Switch the Astra wrapper to use Astra's `direct_FP3D` and `direct_BP3D` functions for 3D Astra geometries. These functions provide a more concise interface and avoid unnecessary data copies. This...

## Description `AstraBackProjector2D.__init__()` and `AstraForwardProjector2D.__init__()` create Astra projector objects, but never delete them (using `astra.projector.delete(proj_id)`) as far as I can tell. A small complication is that these functions can also...
