Device and method for generating a virtual anatomic environment
First Claim
1. A method for producing a three-dimensional, computer generated virtual anatomic environment for use in a computer based visual simulation of minimally invasive surgery, comprising the steps of:
- providing a three-dimensional, computer generated main virtual anatomic environment,selecting a local anatomic environment from a predefined library comprising a set of two or more local anatomic environments, all of the local anatomic environments of the library being separately modelled three-dimensional, computer generated models each representing a distinct, individual anatomic variation in a local internal area of a living being,including the selected local anatomic environment in said main virtual anatomic environment to form said three-dimensional, computer generated virtual anatomic environment, the selection of different combinations of selected local anatomic environments in said main virtual anatomic environment thereby allowing generation of different virtual anatomic environments, each different virtual anatomic environment representing anatomic variations occurring in living beings,providing the virtual anatomical environment in an interaction simulation device, andperforming the visual simulation in the interactive simulation device using the virtual anatomical environment.

Abstract
This invention relates to a method for generating a virtual anatomic environment for use in minimally invasive surgery simulation, comprising the steps of: incorporating a main virtual anatomic environment (1); selecting a local anatomic environment (2) from a predefined library (3) comprising a set of two or more simulated local anatomic environments (2); including the selected local anatomic environment (2) in said main anatomic environment (1) to form a total virtual anatomic environment (4). The invention also relates to a device for generating a virtual anatomic environment for use in minimally invasive surgery simulation, as well as a computer-based minimal-invasive surgery simulation system comprising such a device.
