During 3D acquisitions, lighter and darker patient images may be captured, which may result in less accurate 3D reconstruction. The variation of brightness is a result of a constant unregulated medium dose and the angular change of patient diameter caused by rotational acquisition. This may result in unintentional low-dose radiation exposure to a patient.
