Abstract

In a visualization system and method for visualization of data that relate to a medical intervention at a patient, a surgeon has no visual contact with a surgical instrument but can visualize in the form of a projected geometrical shape by a visualization device, the geometrical shape corresponding to the position and orientation of the surgical instrument onto the body surface of the patient under which the surgical instrument is located with a characteristic of the geometrical shape indicating the distance of the surgical instrument from the body surface.
