<p>An image guided surgery system comprises a position detection system (3, 4ab) which measures the position of a surgical instrument (11) and displays the surgical instrument in its corresponding position in a CT-image or an MRI-image. The position detection system is provided with an indicator system (3, 4) which shows a region for which the position detection system is sensitive. Preferably, the camera unit (1) of the position detection system incorporates a semiconductor laser which generates a light spot in the centre of the operating region.</p> |
