Abstract
A medical apparatus for determining a relative spatial position of a planar marker is provided. The medical apparatus has an illumination device configured to illuminate the marker, a detector configured to detect light steered from the marker to the detector, and an evaluation device configured to determine a direction of a tilt of the marker from an analysis of a first value detected by the detector while the marker is illuminated from a first direction and a second value detected by the detector while the marker is illuminated from a second direction.
