Dear Anna, Please use RTK's mailing list for your questions. As far as I know, ASTRA is iterative so it should handle offset detectors. You'll just have minor residual artifacts, see e.g. figure 8 of dx.doi.org/10.1088/0031-9155/58/2/205. Yes, RTK can handle jpeg and png. Any file type that is handled by ITK is handled by RTK. There are no hardware requirements, it just gets slower with poorer hardware. I hope this helps, Simon
