Hi, Your projections in Ankle.mha display a very large value in air. To start with, I would make sure that everything outside the leg is at about 0 in your original Ankle CT data. Note that projecting and reconstructing a CT image will necessarily result in a loss of quality due to the multiple interpolations (during projection and backprojection). I would suggest to use fine pixels in the projections (e.g. --spacing .25) which you can bin during reconstruction (--binning 4,4). Simon
