Preoperative imaging of a patient's heart with truncus arteriosus communis from two different perspectives. (A1–A3) A direct comparison of CT on a 2D screen (2D imaging), (B1–B3) cinematically rendered hologram, and (C1–C3) 3D printing. In (A3), the coronaries (arrows) show only a weak contrast, but the 3D view can be demonstrated as a cinematically rendered hologram (B3). A reconstruction of the coronary structure for 3D printing was not possible in this case (C3).
