Computer-assisted simulation of conventional roentgenograms from three-dimensional computed tomography (CT) data--an...

A computer simulation program (Forensic X-ray Simulation and Identification System, FoXSIS) is presented. FoXSIS calculates conventional X-ray summation images using any scanning parameters from three-dimensional CT data records. All those parameters decisive for X-ray morphology are freely selectable for realistic simulations: focus-object distance, object-film distance, centering of the X-ray beam, the location of the object in the patch of rays, brightness and contrast, as well as parallel and central projection. In addition, distance and angle measurements, as well as enlargements of details are possible. The program may be expected to help in the identification of unknown corpses now, and even more in the future on account of the increased use of clinical computed tomographies.
