Hi, It's easy to generate, you need to offset your detector, either via the RTK geometry or by setting the first coordinate of the origin of your projection to something which makes the projection uncentered. For example, in the geometry : rtksimulatedgeometry -n 180 --proj_iso_x 100 -o g rtkprojectshepploganphantom -g g -o proj.mha rtkfdk -p . -g g -r proj.mha -o fdk.mha You can simulate from a CT image by following this example <http://wiki.openrtk.org/index.php/RTK/Scripts/ForwardProjection>.
