Abstract
The invention relates to an optical navigation system for determining the position of a patient's anatomy of interest. The system comprises a locating device having at least two optical sensors and a patient reference having at least three optical markers. The system also comprises a reflecting device. When the line of sight between the patient reference and an optical sensor is intersected by an obstacle, the optical sensors are configured to measure, for each optical marker of the patient reference, a quantity representing the position of said optical marker in the frame of reference of the locating device from optical radiation originating from said optical marker and having a path reflected by the reflecting device to each optical sensor.
