Description

Contributor guide

Research direction

This issue requests implementation of distance driven projection/backprojection, referencing an existing implementation at https://github.com/RuiLiu1217/GPU Distance Driven projection backprojection. The TIGRE repository is a MATLAB based toolbox for tomographic reconstruction using GPU acceleration. To implement this, one must understand the algorithm from the reference and how to integrate it into TIGRE's existing code structure, particularly the projection and backprojection functions. The issue is old with no further discussion, so the contributor should first familiarize themselves with TIGRE's codebase and then adapt the reference implementation accordingly.
