Re: [Rtk-users] Acceleration of rtkCudaBackProjectionImageFilter

Dear Laura, Interesting, this option is mainly here for improving the memory management. All it does is split your input stack in subsets to do the reconstruction, thus only loading a few projections in the CPU and GPU memory. This is not implemented in the backprojection because we usually keep th

Dear all, I am using the filter "rtkCudaBackProjectionImageFilter" with Python-Wrapping for a self-implemented iterative algorithm. Right now, this backprojection (and therefore my algorithm) is relatively slow since it does not use the full capacity of my GPU. I know that "rtkCudaFDKConeBeamRe
