Trzeszkowska-Rotkegel1 aMichał Tarnawski00aCorrection of error in 3D reconstruction induced by CT gantry tilt  a169–1750 v123 aThe paper presents the problems connected with 3D reconstruction of CT slices of the database of orthodontic patients, using the commercial application software. Serious errors occurred for scans taken with a tilted CT gantry and inverse table movement. A compensation of the errors is proposed and the results after the compensation are verified by comparison to laser scans for a reference object, and to the measurements performed using the dedicated software of the CT station for selected cases in the database.  a1642-6037
