A digital autopsy is a non-invasive autopsy in which digital imaging technology, such as with Computerized Tomography (CT) or Magnetic Resonance Imaging (MRI) scans, is used to develop three-dimensional images for a virtual exploration of a human body.
Digital autopsy, simply, means conducting autopsy in computerized environment by digital tools. The first step of digitizing starts with the medical imaging modalities that provide the raw data images from the deceased. The most common modalities are Computerized Tomography (CT scan) and Magnetic Resonance Imaging (MRI) scanner. Three dimensional medical visualization is the technical process that provide the digital environment for exploration of the 3D body and conducting the digital autopsy.
The term cannot be found before 1985 in the literature. However, there are many other similar terms like: Postmortem CT scanning for individual organs, volumetric radiologic scanning, Virtual Autopsy and Virtopsy.
One of the first documented Digital Autopsy studies was conducted at the department of Neuroradiology, University Hospital Mainz, Germany in the year 1980, where in 105 specimens of human stillborn and live-birth infants, ranging in age from gestational week 13 to postnatal month 18 were studied. Since then the arena of 2D CT scan images has gradually evolved to present day technologies of Multi-planar reconstructions (MPR) and real to life high definition 3D rendering. In the year 1998 various aspects of human and animal anatomy and pathology were successfully studied by Digital 3D examination on the ancient mummified specimens at the Academic Medical Centre, Amsterdam. Similar studies have also since then been done at the British Museum. The digital 3D analysis of data obtained from CT scanning the mummies has helped in visualization of the faces of some of the mummies, including that of chanters from the Temple of Karnak. This technology has also given vast information about the embalming and burial processes. In the year, 2009 CT scanning and digital analysis of DICOM data was successfully used by the VIFM, Australia during the phase 2 of the DVI process for the Victorian bushfires. All dead bodies and scattered remains were CT scanned in their body bags using specific protocols and analyzed. Digital examination helped not only in separating the presence of non-human remains, but also was useful at the time of autopsy to capture and analyze the identifying features in cases of severe disfiguration.
