<div dir="ltr"><div style="font-size:12.8px">Dear rtk-users,</div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">I am having success with forward projection and reconstruction of complete cases much like in the example from the wiki. However, I am interested in creating projections of cropped images. I took the 00.mha from the example and cropped it. When I create the projection, using rtkforwardprojections, the cropped projection rotates around the isocenter of the original uncropped file around the AP axis as expected.</div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">Is there a way to create a projection of a cropped image such that the cropped projection rotates around a newly centered AP axis?</div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">I am certain that the origin and spacing values of the geometry are correct. I have tried messing with the sid and the sdd values but they do not influence the distance between the isocenter and the cropped object.</div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">Thanks</div>
