Dear rtk-users
I am now working on iterative reconstruction offset detector CBCT
using my elekta data.
However, probably because the data is truncated , the ring artifact
appears in the iterative reconstruction.
One of the reasons was that flat field correction was not performed.
Is flat field correction possible with RTK?
I don't have an image for flat field correction, so are you predicting
it? Or do I have to have a flat field correction image?
Thank you very much in advance
