Virtual endoscopy in CT is a function in which internal structures of the human body can be observed interactively while moving the viewpoint. This function is realized by image processing of the 3-dimensional volume data. It also allows structures that cannot be observed using a real endoscope to be examined with low invasiveness. The Toshiba X-ray CT system Aquilion Super Heart Edition supports scanning of 16 slices in 0.4 second as well as the virtual endoscopy function as a clinical application. This paper describes the techniques employed in virtual endoscopy and also discusses other applications that are related to this technique.
