Cone-beam artifact reduction in Gamma Knife CBCT images using a line-arc-line scan trajectory
Alexandra Alain-Beaudoin, Håkan Nordström, Luc Beaulieu +1
Objective. Gamma Knife cone-beam computed tomography (CBCT) images suffer from distinct cone-beam artifacts for some patients, due to the conical X-ray beam which is oriented to in…

Non-circular scan trajectories for reducing cone-beam artifacts in Gamma Knife CBCT images: a simulation study
Alexandra Alain-Beaudoin, Håkan Nordström, Luc Beaulieu +1
Objective. Gamma Knife cone-beam computed tomography (CBCT) images are deteriorated by cone-beam artifacts whose magnitude increases along the superior direction. In this study, a…
