Hello, We are having problems with the SIRT reconstructions. They seem very strange and blurry. However, other reconstructions (SART, FDK, iterativeFDK) look perfect. I uploaded an example of a SART and a SIRT reconstruction (same parameters) to https://www.dropbox.com/sh/7a4bkyjg43zjmy7/AAAp4tJrk9HedMEEuIKsGYDSa?dl=0. I also uploaded a minimalistic version of the code that I used (the paths in CMakeLists.txt probably need to be adapted to your system). You can alternate between SART and SIRT by changing line 143. The raw data is also available on dropbox. I didn't use rtkXRadRawToAttenuationImageFilter, because our projections are already corrected for the dark field and flood field, so (signal-dark)/(flood-dark). I just take the natural logarithm and multiply by -1. Do you know what could be the problem with the SIRT reconstructions? Are we using wrong parameters? Thanks for your time.
