Research|interactive Medical Simulation



Present day surgical training involves extensive use of cadavers and animals. Only a few trainees can practice at a time and they can hardly encounter rare medical conditions during the course of their study. Besides, objective quantitative assessment of their skills is difficult. To circumvent these problems and to provide surgeons with almost inexhaustible training materials, there is significant interest in digital surgery or the use of computer generated models to help train surgeons; much like fight simulations are used today to successfully train aviation pilots. Such a simulator would allow the trainee to interact with virtual 3D graphical models of human organs while manipulating them using a force feedback device such as a Phantom. Better trained surgeons and residents would translate to better prepared surgeons in the operating room, leading to fewer errors and morbidity.
