An image-guided surgery system includes an optical position measuring system (1, 2) for measuring the position of a surgical instrument (13) relative to a patient (14) to be operated or treated. Using a data processor (2), the position of the surgical instrument (13) is reproduced in an image displayed on a monitor (16). The optical position measuring system (1, 2) includes a camera unit (1) with two cameras (10). The camera unit (1) also includes a memory unit (3) in which data concerning the positions of the cameras (10) in the camera unit (1) relative to one another are stored. |
