Abstract
A system for orientation assistance and display of an instrument that is inserted or present in the natural or artificially produced hollow cavity (human, animal, object), and that is equipped with one or more sensor units. Multiple measurements of the 3D position of the instrument equipped with one or more sensor units are performed by positioning a measuring system, so that a precise orientation and positioning of the instrument in the body can be computed. The 3D position data are used to compute a virtual image of the instrument synchronously. The virtual images are then either projected directly in exact position onto the body surface of a person or combined in a body surface image (real video camera image of the patient) onto a monitor or superimposed (virtual or augmented reality). The system is especially appropriate for displaying for a user a medical instrument, such as a catheter or a rigid or flexible endoscope, in the body of a person in real time, extracorporeally and in correct position.
