AbstractIn a case of murder by a single .22 caliber bullet fragmented in the head, determination of the trajectory was a key issue in identifying which of 2 windows, 1 of which was associated with 2 suspects, was the site of fire. For this purpose, we processed the computed tomography of the victim's head by using a radiation therapy planning system called Plato, which is routinely used in radiation oncology. This tool provided a 3-dimensional reconstruction of the cranio-cerebral lesions and a spatial location of bullet and bone fragments. In this article is described the more intuitive relationship with forensic and ballistic data obtained from the 3-dimensional visualization and the physical and mathematical analysis used to calculate the angle of shot.
