<p>A simulator for simulating treatment of biological tissue comprises a real handle with three degrees of freedom of both translation and rotation, a screen for displaying a model of the treatment area and a virtual handle, a motion detection device for detecting the three-dimensional motion of the real handle, and a computer having a simulation program that displays the virtual handle on the screen in spatial relation to the biological tissue on the basis of the motion of the real handle detected by the motion detection device. The real handle simulates a laser head that emits a laser beam for treating the biological tissue. The simulation program calculates an impinging surface of the laser beam on the biological tissue based on the spatial relation and laser parameters and calculates an energy density distribution of the laser beam within the impinging surface. The removal of tissue is displayed on the screen.</p> |
