Autopsy imaging, also known as postmortem computed tomography (PMCT), is widely used in Japan as an alternative screening method when permission for a conventional autopsy has not been given. When permission has been granted it is also used to supply supplemental information to assist the medical examiner during the autopsy. Plans are in progress to establish a postmortem image data accumulation center in Japan and to carry out a feasibility study for a computer-aided diagnosis (CAD) system.
