Have a look at the inside of a human being - dead or alive. By using the latest technique within medical visualization it is possible to use the virtual autopsy table to study the details in the 3D-images of the scanned bodies. |
The Virtual Autopsy Table is a unique new medical visualization tool that allows people to explore the inside of a human body. With its intuitive gesture based interface, the Virtual Autopsy Table totally changes the way users interact with volumetric medical data. Multiple users can interact collaboratively and simultaneously, working with large and complex data to gain deeper understanding and insight into the functions and processes inside the body. |

Virtual Autopsy is already utilized successfully to complement conventional autopsies. It dispenses with the need for invasive surgical procedures allowing medical experts to see things that would be difficult to discover with traditional methods. The technique can also be applied in many other areas of health and medical practice. |

Case 1 – Traffic accident victim |
|
|
The data set shows a full-body examination of a traffic accident victim. The examination gives the viewer a good and quick understanding of the 3D post-mortem anatomy and a possible cause of death, in this case a broken neck. Notable fractures: On the right middle foot, left tibia and fibula, right knee and left femoral shaft, fractured jaw and a broken vertebra.
Scanning technique: Computed Tomography
Physical size: 384 x 384 x 1699 mm
Sample resolution: 512 x 512 x 3397
Size on disk: 1.7 GB

Case 2 – Computed tomography of brain vessels |
|
|
A living patient was treated for cerebral hemorrhaging. X-rays sent through the body during computed tomography grow weaker according to the density of the tissue through which they pass. By assigning density values with varying degrees of transparency and identifying colors, a sort of palette can be created by the computer to use in the imaging process. It becomes possible, for example, to remove clothing, skin or blood vessels. In this case the patient has been operated for a ruptured aneurysm in a small brain vessel. A metal clips has been added that can be seen in the image.
