Bow-tie wobble artifact: Effect of source assembly motion on cone-beam CT

Purpose: To investigate the cause of a bow-tie wobble artifact (BWA) discovered on Varian OBI CBCT images and to develop practical correction strategies.Method and Materials: The dependence of the BWA on phantom geometry, phantom position, specific system, and reconstruction algorithm was investigat...
