Evaluation of the effects of sagging shifts on isocenter accuracy and image quality of cone‐beam CT from kV on‐board imagers
To investigate the effects of sagging shifts of three on‐board kV imaging systems (OBI) on the isocenter positioning accuracy and image quality of cone‐beam CT (CBCT). A cubical phantom having a metal marker in the center that can be aligned with the radiation isocenter was used to measure sagging s...
