Abstract: A tracker, a surgical tracking system, and a method for operating the tracker are provided. The tracker comprises an interface configured to attach the tracker to a surgical object that is to be tracked. The tracker further comprises circuitry comprising a detector configured to detect electromagnetic radiation, wherein the circuitry is configured to generate a trigger signal upon detection of a change of intensity of electromagnetic radiation by the detector. The circuitry further comprises a plurality of emitters configured to emit electromagnetic radiation, wherein the circuitry is configured to control the plurality of emitters to emit electromagnetic radiation responsive to the trigger signal.

Abstract: A technique for determining a need for a re-registration of a patient tracker with medical image data of a patient is presented. The patient tracker comprises an acceleration sensor configured to generate inertial data indicative of an acceleration of the patient tracker. A method implementation of the technique comprises the following steps performed by a processor: receiving inertial data acquired by the acceleration sensor, analyzing the received inertial data, or data derived therefrom, with respect to at least one first predetermined condition indicative of a drift of the tracker or an impact on the tracker, and generating, when the at least one first predetermined condition is fulfilled, at least a first re-registration signal.

Abstract: A method, computer program product, device, and tracking system for assigning marker identities to markers of a tracker are provided. The tracker includes a reference detectable in a visible light spectrum, and the markers are detectable at least in an infrared light spectrum. The markers are arranged in a pre-determined relationship relative to the reference and the pre-determined relationship is indicative of the marker identities. A method implementation includes receiving first image data of the markers captured in the infrared spectrum. The method further includes receiving second image data of the reference captured in the visible light spectrum. The first and second image data may be captured under at least essentially the same viewing angle. The method further includes assigning the marker identities to the markers determined in the first image data based on the reference determined in the second image data and the pre-determined relationship.
