How can I choose the appropriate parameters of filters, such as Hann hannY multiplier radius.

When I run rtkfdk.exe with these parameter input, my CPU go to 100％, I have to close cuda acceleration. subsetsize didn’t work. I have to use --lowmem. But running rtkfdk with --lowmem have a very slow speed.

THE image size and pixel size of 2D IMAGE is 768×768 and 0.56mm/pixel

  1. Hann windowing is a trade off between spatial resolution and noise. There is no good answer, you need to test several values and adapt it to your needs.
  2. I don’t fully get the issue… The issue description seems to be a mix between CPU usage and memory consumption. Use lowmem if you want to reduce the memory footprint. Yes, it can decrease a bit the performances. In any case, tomographic reconstruction uses computing ressources, there is no alternative…
