The importance of autopsy procedures leading to the establishment of the cause of death is well-known. A recent addition to the autopsy work ﬂow is the possibility of conducting postmortem imaging, in its 3D version also called virtual autopsy (VA), using multidetector computed tomography (MDCT) or magnetic resonance imagining (MRI) data from scans of cadavers displayed with direct volume rendering (DVR) 3D techniques. The use of the data and their workﬂow are presented. Data acquisition was performed and high quality data-sets with submillimeter precision were acquired. New data acquisition techniques such as dualenergy CT (DECT) and quantitative MRI, then were implemented and provided additional information. Particular ﬁndings hardly visualized in conventional autopsy can rather easy be seen at the full body CT, such as air distribution, e.g. pneumothorax, pneumopericardium, air embolism, and wound channels. MRI shows natural deaths such as myocardial infarctions. Interactive visualization of these 3D data-sets can provide valuable insight into the corpses and enables non-invasive diagnostic procedures. In postmortem CT imaging, not being limited by a patient depending radiation dose limit the data-sets can, however, be generated with such a high resolution that they become difﬁcult to handle in today’s archive retrieval and interactive visualization systems, speciﬁcally in the case of full body scans. To take full advantage of these new technologies the postmortem workﬂow needs to be tailored to the demands and opportunities that the new technologies allow.
