Abstract: A controller for a surgical navigation system is presented. The controller is configured to receive a position signal from a tracking system, wherein the position signal is indicative of a position of a hand-held surgical device that is tracked by the surgical navigation system inside an operation environment. The controller is further configured to receive sound signals from a plurality of microphones directed toward the operation environment, wherein the sound signals potentially contain one or more voice commands from one or more voice sources inside the operation environment. The controller is configured to process the sound signals dependent on the position signal.

Abstract: A tracker, a surgical navigation system with the tracker, and a method of operating the tracker are described. The tracker comprises a first switch configured to be operated between a first switch configuration and a second switch configuration. The tracker also comprises one or more sources of electromagnetic radiation configured to selectively emit electromagnetic radiation with a first radiation characteristic or a second radiation characteristic. The tracker further comprises electrical circuitry configured to selectively control the one or more sources of electromagnetic radiation to emit electromagnetic radiation having the first radiation characteristic in the first switch configuration and to emit electromagnetic radiation having the second radiation characteristic in the second switch configuration, wherein the second radiation characteristic is different from the first radiation characteristic.

Abstract: An adapter for removably coupling a tracker to a surgical handpiece includes a proximal member having an interface configured to engage and prevent rotation of the proximal member relative to the surgical handpiece, a distal member slidably and rotatably coupled to the proximal member, a biasing member disposed between the proximal distal members and configured to urge the proximal and distal members in opposing directions, and a tracking array mount coupled to the distal member. The biasing member is configured to be compressed by a reference feature of the end effector and the surgical handpiece when the distal member is disposed on the end effector and the end effector is coupled to the surgical handpiece, the compressed biasing member creating a frictional force between the distal and proximal members that resists rotation of the distal member relative to the proximal member.

Abstract: A method, a computer program product, a device, and a surgical navigation system for determining a marker arrangement that defines positions of markers of a tracker are provided. The markers are detectable by a first imaging modality and a second imaging modality that is different from the first imaging modality. The method comprises receiving first image data of the markers that were captured using the first imaging modality and receiving second image data of the markers that were captured using the second imaging modality. The method further comprises determining the marker arrangement based on the first and second image data.

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.
