[Rtk-users] RTK Python Wrapper—Missing CudaFDKBackProjectionImageFilter and Update Request

[Linxi Shi]

Hi Simon,
We’re a Silicon Valley startup building 3D image guidance for surgery.
At a high level: our product uses RTK. We initially installed the precompiled package via:
python -m pip install itk-rtk-cuda116
Everything worked until we uncovered a quantitative mismatch in the reconstruction, which we traced to a missing filter-CudaFDKBackProjectionImageFilter-that (per your note on our issue thread<https://github.com/RTKConsortium/RTK/issues/835>) wasn’t included until June 4 so it is confirmed that it is missing in our version.
We see the instructions<https://docs.openrtk.org/en/latest/INSTALLATION.html> now reference cuda124, but we’re not sure whether the Python wrapper/CI has been updated to include this filter. Could you confirm if there’s an updated wrapper that contains CudaFDKBackProjectionImageFilter? If not, we’d appreciate guidance on the best workaround.
We’ve been stuck for long. Thanks so much for your help on this.
Best,
Linxi
