Abstract: A method for determining arrangement data which represents an arrangement of measurement points on an anatomical structure of a patient, wherein the arrangement data is individually determined for different regions of the anatomical structure.

Abstract: A method for determining a characteristic property of an anatomical structure from scan data which represents the position of scan points on the surface of the anatomical structure, wherein a spatial region is defined, the scan points which lie in the spatial region are determined, and the scan points which are determined to be lying in the spatial region are used to determine the characteristic property.

Abstract: A system and method for determining the position of correspondence object pairs including A-objects and B-objects that represent the same objects of the same anatomical body structure in two different reference frames A and B, including: defining A-objects and B-objects that each represent different objects of the body structure in their respective reference frames; determining geometric relationship data A and geometric relationship data B that describe a geometric relationship between the A-objects based on positions of the A-objects in the reference frame A and the B-objects in the B reference frame; and providing data derived or extracted from the geometric relationship data A and from the geometric relationship data B to allow a comparison of a geometric relationship between at least two A-objects to a geometric relationship between at least two B-objects.

Abstract: A method for generating a three-dimensional model of a part of the body with the aid of a medical and/or surgical navigation system, comprising the steps of identifying to the navigation system landmarks on the part of the body that are characteristic of the model of the part of the body; obtaining at least two fluoroscopy image data sets for each of one or more predetermined, individual and delimited regions of the part of the body; ascertaining characteristic body part data by processing and combining the landmark positions and parameters of the fluoroscopy data sets; and generating a three-dimensional and positionally determined model of the part of the body from the characteristic body part data.
