Abstract
Modern multislice CT systems with a fast rotating gantry are particularly suitable for cardiac volume imaging. Due to the cone angle, true 3D back-projection algorithms deliver superior image quality compared with 2D techniques. We propose a true cone-beam reconstruction algorithm making use of the maximum amount of the measured data in combination with retrospective cardiac gating. Results are presented on a patient data set, which has been acquired using a 16-slice CT system.
