Abstract

A method and a system are for simulating a surgical procedure on a bodily object, such as an organ, in a virtual environment. The virtual environment includes a three-dimensional mathematically described model of the bodily object which reflects geometrical and mechanical properties, and a virtual instrument that is controlled by a physical feeding device, which makes it possible to affect the model. The method includes the steps of representing a two-dimensional projection of the model by way of a video sequence containing a recorded view of a real bodily object, wherein engagement with the virtual instrument only involves interacting with the model. In addition, a method is for simulating an operation containing several surgical procedures.
