Abstract

A newly developed software-based compensation of geometrical misalignments is applied to several computed tomography (CT) instruments. The actual geometry of each CT instrument is measured using a dedicated procedure. Then, given the measured geometries, software-based compensation is applied. Dimensional measurements on a validation object show a consistent reduction in observed errors as a result of the compensation. Robustness of the compensation method is confirmed also on a CT instrument with severe misalignments.
