A virtual reality system for simulating medical processes is described, which may include a variety of features and functions, and may implement a variety of processes. In a typical illustrative situation, the virtual reality system supports a system in which a virtual medical procedure may be performed on a virtual patient (or a part thereof), the virtual patient having medical conditions that simulate those of an actual real-world patient. The virtual reality system enables a user, such as a physician, to develop a strategy for treating the actual patient by performing one or more procedures on a simulated virtual patient.
