Abstract

A method for verifying the position of at least two bone structures relative to each other, comprising the method steps of: recording a three-dimensional dataset which represents the bone structures; segmenting the three-dimensional dataset into segments, wherein each segment represents a bone structure and the segments exhibit a known relative position in the three-dimensional dataset; changing the virtual relative position of the segments, such that the virtual relative position of the segments matches the actual relative position of the bone structures; and verifying whether the virtual relative position of the segments matches a target position of the bone structures.
