System und Verfahren zur aktuell exakten Erfassung von Behandlungszielpunkten

Abstract

System zur Erfassung von Behandlungszielpunkten für die chirurgische Navigation mit einer computergestützten Referenzierungseinrichtung, die positionsgebende Reflektoren und Marker sowie eine erste Positionsdetektionseinrichtung aufweist und Diagnose-Bilddaten eines Patienten mit den ermittelten Positionswerten von Behandlungsgeräten und Patienten-Körperabschnitten zur navigationsunterstützten Behandlung verknüpft, bei dem eine zweite Positionsdetektionseinrichtung vorgesehen ist, die in die Referenzierungseinrichtung eingebunden wird und mit deren Positionsinformationen die Positionswerte aus der ersten Positionsdetektionseinrichtung aktualisiert werden, dadurch gekennzeichnet, dass die zweite Positionsdetektionseinrichtung eine Magnetfelderzeugungseinrichtung aufweist, welche in ein Behandlungsziel eingebracht oder in dessen Nähe positioniert ist, sowie einen Detektor zur Bestimmung der Ausrichtung und Position der Magnetfelderzeugungseinrichtung.
