Hi! I have a slightly non-typical task. I've got a detector with a vertical gap that is not equal to pixel, so if I just insert interpolated pixel(s) to projection then corresponding geometry artifacts appear. https://i.imgur.com/1gwW1vx.png
In order to take full account of the gap I'm trying to reconstruct my volume twice. So there are two sets of projections on opposite sides of the gap. I passed simple steps: - firstly reconstruct volume for the left side with correct offset that takes into account the gap; - reconstruct volume for the right side with also correct offset and initial volume from previous reconstruction; The volume obtained by this sequence does not suffer from geometry artifacts! However, there is a bright point in the center of the volume and the lines that come out of it. https://imgur.com/nUJ1IW5. Obviously, it's related to projection's edge, just like a fov circle in usual reconstruction. Is there any way to get rid of it ?
