Dear Tobias, The forward projection has 2 inputs: - input 0: the stack of projections in which you wish to forward project, - input 1: the volume you wish to forward project. For the backprojection, it's exactly the same: - input 0: the volume in which you wish to backproject, - input 1: the stack of projections you wish to backproject. Be aware that JosephBackProjectionImageFilter is the transpose of the forward projection and will have some aliasing (see, e.g., De Man and Basu <http://iopscience.iop.org/article/10.1088/0031-9155/49/11/024/meta;jsessionid=87B598ABFDC2AA07D1DED2DEE607F0E7.c2.iopscience.cld.iop.org> to see what I mean). I have personally never used MITK but don't hesitate to share your experience on the mailing list. Simon
