Model-based approach to minimize system calibrations for 3D reconstruction quality of a cone-beam CT system

Obtaining high quality medical 3D reconstructions is of increasing importance for the medical community. The quality of a 3D reconstruction depends heavily on accurate knowledge of the position and orientation of the detector and X-ray source during a reconstruction scan. New developments in the considered class of medical imaging systems tend to lightweight design and an increasing number of scan positions. In this work, an alternative model-based approach is introduced for the currently used geometric system calibrations.
