Visual Rendering Engine for Virtual Reality Surgical Training Simulator

摘要

Exemplary embodiments of a virtual reality surgical training simulator may be described. A virtual reality surgical training simulator may have a rendering engine, a physics engine, a metrics engine, a graphical user interface, and a human machine interface. The rendering engine can display a three-dimensional representation of a surgical site containing visual models of organs and surgical tools located at the surgical site. The physics engine can perform a variety of calculations in real time to represent realistic motions of the tools, organs, and anatomical environment. A graphical user interface can be present to allow a user to control a simulation. Finally, a metrics engine may be present to evaluate user performance and skill based on a variety of parameters that can be tracked during a simulation.

主权项

1. A method of generating a virtual reality simulation in three dimensions for a virtual reality surgical simulator, comprising:
receiving a command to initialize a simulation; initializing a connection to one or more connected rendering, physics, and metrics engines; loading into the one or more connected rendering engines at least one initial state description file that is appropriate to render an initial state of a graphical user interface, wherein the graphical user interface is configured to provide an interface having secondary information in a periphery of the graphical user interface and a configurable main panel in a central area of the graphical user interface; composing a first set of machine-readable instructions for generating the initial state of the graphical user interface by the one or more connected rendering engines; transmitting the first set of machine-readable instructions to a processing system; and causing the initial state of the graphical user interface to be displayed on at least one connected output device having a plurality of configuration option icons displayed in the main panel configured to allow a user to change the configuration or state of a virtual reality surgical simulator system on selection of one or more icons.
