Dual-domain network with transfer learning for bowtie-filter induced artifacts in half-fan cone-beam CT

, 2022
In a cone-beam CT system, the use of bowtie-filter may induce artifacts in the reconstructed images. Through a Monte-Carlo simulation study, we confirm that the bowtie filter causes spatially biased beam energy difference thereby creating beam-hardening ...

Respiratory motion correction in cone-beam CT for image-guided radiotherapy

, 2013
International audienceCone-beam CT has been integrated with the linear accelerator for image-guided radiotherapy, i.e., the accurate assessment and correction of the target position prior to treatment delivery. The slowness of these cone-beam CT scanners,

Parallel Implementation of the Katsevich's FBP Algorithm

International Journal of Biomedical Imaging, 2006
For spiral cone-beam CT, parallel computing is an effective approach to resolving the problem of heavy computation burden. It is well known that the major computation time is spent in the backprojection step for either filtered-backprojection (FBP) or ...
