Hi RTK users, I am trying to simulate motion artifacts in a phantom model. I have created a group of numberical phantoms, each one slightly shifted but with the same FOV, volume and origin. I am using the corresponding stack of projection files and an amsterdamshroud signal as an input to rtkfourdfdk
However, I am getting an error that says :"Cannot account for too large detector displacements, a part of space must be covered by all projections. My phantoms are 2800,2800,20 with a spacing of 0.04 mm. My questions are how can I resolve this error, and is rtkfourdfdk even the function I want to use in the first place? Should I instead be trying to "compensate motion" on a static image? The end goal is to simulation motion artifacts that could be present in cardiac CTs. Thanks, Solomon
