In forensic medicine, the study of motor vehicle accidents occurs frequently. The situation of the impact is a crucial consideration in the examination of accident victims, such as in incidents between motor vehicles and pedestrians or cyclists. Three-dimensional technologies and methodologies are becoming more significant in forensic investigations in addition to forensic medical examinations (including autopsies and external examinations). In addition to using post-mortem multi-slice computed tomography (MSCT) and magnetic resonance imaging (MRI) to record and analyze interior results, extremely accurate 3D surface scanning is used to record external body findings and injury-causing objects. The relationship between the body's injuries and the accident mechanism and object that caused the injuries is crucial. Documenting the external and interior body, the involved vehicles, the inflicting tools, and analyzing the collected data are some of the applicable ways. By using 3D surface scanning, the body surface and the damaged accident cars were digitally captured. Post-mortem MSCT and MRI were employed for the body's interior discoveries. The analysis included converting the acquired data into 3D models, determining the vehicle's driving direction, relating injuries to vehicle damage, determining the impact situation geometrically, and assessing additional accident-related findings. The advantages of using 3D documentation and computer-assisted, drawn-to-scale 3D comparisons of the pertinent injuries with the vehicle damage in the study of accident progression, particularly with regard to the impact situation, are demonstrated in the following article using two studied examples.
