What's Changed Summary SIRF/STIR The implementation of the creation of sirf.STIR.ImageData from sirf.STIR.AcquisitionData has been revised to ensure compatibility of ImageData dimensions and voxel sizes with AcquisitionData. Missing __del__ added to sirf.STIR.AcquisitionModel. SIRF/Registration sirf.Reg.ImageData stores voxels values in a 3D Fortran-style array, hence strides had to be set in ImageData.__array_interface__ accordingly (other SIRF ImageData objects use default C-style). Python interface Restored functionality for algebraic operations mixing SIRF data containers and numpy arrays and corrected the description of the result type in User Guide. Error raised if AcquisitionModel.adjoint ran when the model is not linear. SIRF Adjoint operator added in common/SIRF.py. Added initial pytorch wrappers and examples, check torch/README.md. Simplified sirf.Utilities.Handle for SWIG backend calls. Contributions details CITATION.cff and mailmap updated by @KrisThielemans in https://github.com/SyneRBI/SIRF/pull/1354.
