Medical Simulation: Recent Advances and Key Challenges
Medical simulation is a cross-disciplinary effort that integrates, within a single environment, leading-edge research from biomechanical modeling, contact modeling, computer simulation, virtual reality, and human factor engineering. State of the art medical simulations aim to imitate real patients, anatomic details, clinical tasks, and medical experience that mirror the real-life situations in which medical services are rendered. Emerging computer-based virtual reality technologies (e.g. 3D data modeling and visualization together with haptic interaction) have already demonstrated huge potential for improving healthcare treatment and training. As surgical robots (such as da Vinci robot) increase in visibility and popularity, robot-assisted surgical training has become critical, as an increasing numbers of patients are opting for minimally invasive surgery with its promise of quicker recoveries and less pain. Computer-based training systems promise realistic, customized and conﬁgurable training environments, as well as tools to assess clinical knowledge and decision-making skills of physicians and nurses. Procedure-specific software applications for hands on surgical training are currently available for several commonly performed surgical procedures.
There are several challenges facing the medical simulation community, the foremost among them being realism, which entails accurate modeling of the physiological system, obtaining computational solutions in real-time and 3D visualization in the virtual reality environment. Due to the nonlinear and anisotropic behavior of human tissue, its modeling poses a major challenge to the biomechanical engineering researchers. Physics-based approaches to tissue modeling can produce realistic behaviors but, until recently, were unable to achieve the required real-time performance. The use of graphic processors with its superior computational capabilities has made possible speedy rendering of virtual objects. Human computer interaction involving visual, auditory, haptic, and olfactory displays is major challenge in medical simulators. Simplicity of use, effective training of the medical personnel and speedy integration into clinical environment also pose challenges. This talk will focus on the recent advances and key challenges in the medical simulation field.
