Optimized x-ray source scanning trajectories for iterative reconstruction in high cone-angle tomography

Kingston, Andrew; Myers, Glenn; Latham, Shane; Li, Heyang (Thomas); Veldkamp, Jan P.; Sheppard, Adrian


With the GPU computing becoming main-stream, iterative tomographic reconstruction (IR) is becoming a com- putationally viable alternative to traditional single-shot analytical methods such as filtered back-projection. IR liberates one from the continuous X-ray source trajectories required for analytical reconstruction. We present a family of novel X-ray source trajectories for large-angle CBCT. These discrete (sparsely sampled) trajectories op- timally fill the space of possible source...[Show more]
