Medical imaging is the technique and process of creating visual representations of the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues (physiology). Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease. Medical imaging also establishes a database of normal anatomy and physiology to make it possible to identify abnormalities. Although imaging of removed organs and tissues can be performed for medical reasons, such procedures are usually considered part of pathology instead of medical imaging.

Digital Autopsy cannot be found as a term before 1985 in the literature. However, there are many other similar terms like: Post mortem CT scanning for individual organs, volumetric radiologic scanning, Virtual Autopsy and Virtopsy. 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.
