[Rtk-users] ThreeDCircularProjectionGeometry Angular Arc

[Benjamin W. Maloney]

Hi all,

I had a question about the angular arc of projections fed into the ThreeDCircularProjectionGeometry to be used in an FDK Cone Beam Reconstruction.

The hardware for the CT system I'm using is not capable of moving exactly 360 degrees as part of a scan. If I know the angular step well is it better for the projections to cover slightly less or slightly more than 360 degrees?

Can RTK handle arcs larger than 1 full rotation or arcs slightly less than 1 full rotation without errors?

My assumption is that slightly largely is best to avoid artifacts but I want to verify that RTK can handle larger rotations without errors

Best,
Ben
