Transperineal Ultrasound-Guided Biopsy Simulator

Health care professionals can use high-fidelity virtual training simulation (VTS) so that necessary procedures may be practised and refreshed before operating on a real person. Advantages of relying on such controlled learning environments includes; zero patient risk, development of psychomotor skills for the medical tools and the opportunity to experience challenging ‘what if’ scenarios. In this theme we explore the use of haptics in a series of haptic-enabled biopsy simulators, such as Transperineal Prostate and Kidney biopsies. We couple haptic devices, such as Phantom Omnis with novel interfaces such as zSpace stereoscopic display and Oculus Rift.

During a transperineal prostate biopsy, the needle is injected through the grid, which is placed against the perineum, into the prostate and a sample is selected. Our prototype uses physical props for the body with a grid attached, a Geomagic Touch and a G-Coder Simball 4D. The main guiding visualization for the process is the ultrasound display mock-up.
