Application of Korean Mechanical 3D Bone Model to the MADYMO(R) / 대한법의학회지

MADYMO(R) (Mathematical Dynamic Models) is a computer software with a multibody dynamics solver, which can be employed to reconstruct and interpret dynamic motions of the human body in impacts. The human model of the software is composed of many ellipsoidal structures, which makes it possible to interpret dynamic whole-body motions and calculate applied forces to human body parts. However, this model has some disadvantage to interpret injuries of the smaller body parts such as ribs, vertebral bodies or intervertebral discs. After achieving the finite element bone model produced by CT and software BIONIX BODYBUILDER(R) (finite element modeller), we tried to import this model into the MADYMO(R) and parts of the human bone model were successfully imported to it. Importing of the whole bone model was, however, impossible because of the numerous elements. The coming experiments need to reduce the number of elements in the whole human bone model and incorporate ligaments, tendons and muscles into each separated part of bone models.

The plausible practicality of modern high-tech medical imaging devices to forensic medicine and scientific crime investigation / 대한법의학회지

CT and MRI are high-tech devices for medical diagnosis. Their electromechanical function has leaped forward such a fast step, so that their image quality is improved and the time for a whole body scanning is shortened as little as only several minutes. These essential diagnostic tools are tried to apply for the field of forensic medicine in favor of their noninvasiveness and great resolution. These merits could make our postmortem investigation system improve in the aspect of practicality. This presenting study was done for the purpose of expecting what the field of forensic medicine could get or lose, what is needed technically, and what kind of supports are required. In our preliminary study, we gave injuries to the pigs' heads with weapons, scanned the wounds with high-tech devices, and embodied the injuries and the weapons three-dimensionally. These high-tech methods would be expected to play a role in forensic medicine and scientific crime investigation as a new and powerful testimony.
