摘要： Apparatus, including a patient tracker, attached to a subject, having magnetic field sensors and optical landmarks with known spatial relationships to each other. A camera acquires a 3D optical image, in a first frame of reference (FOR), of the subject's face. A magnetic radiator assembly generates magnetic fields at the subject's head, thereby defining a second FOR. A processor: processes field sensor signals to acquire location coordinates of the sensors in the second FOR; segments a tomographic image of the subject, having a third FOR, to identify the subject's face in the third FOR; computes a first transformation between the third and first FORs to map the tomographic face image to the 3D optical image; maps the optical landmarks to the third FOR; maps the respective location coordinates of the sensors to the first FOR; and computes a second transformation between the second FOR and the third FOR.

摘要： Tools used within a surgical area may be equipped with sensors that allow them to be tracked within the magnetic field of an image guided surgery (IGS) system. These tools may include a probe which is instrumented with a position sensor allowing it to be used not only for registration of non-magnetic objects within the magnetic field, but also for providing additional inputs.

摘要： An ENT surgical instrument includes a shaft assembly, a flexible substrate, and at least at least one electrically-conductive sensor trace formed on the flexible substrate. The shaft assembly has a distal end sized and configured to fit in an anatomical passageway in an ear, nose, or throat of a patient. The flexible substrate extends along at least a portion of the shaft. The at least one sensor trace includes at least one concentric loop portion, wherein the at least one concentric loop portion defines at least one navigation sensor.

摘要： Apparatus, including an enclosure having a base and a cover with respective conductive layers. The conductive layers connect to form a shield attenuating electromagnetic radiation originating outside the enclosure in a range of 10 kHz-100 kHz by at least 20 dB within the enclosure. An adapter circuit within the enclosure processes electrophysiological signals to generate an output signal. A first connector passing through the enclosure connects to a probe to receive the electrophysiological signals and convey them to the adapter circuit. A second connector passing through the enclosure receives the output signal from the adapter circuit and conveys it to a console. A control input receives a control signal indicative of a frequency within the range, and a sensing circuit senses a magnetic field within the enclosure and outputs a warning signal when the magnetic field at the frequency indicated by the control signal exceeds a preset threshold.

摘要： A medical apparatus includes a probe including a handle having a longitudinal axis, a distal tip disposed on the longitudinal axis, and a position sensor, which is disposed in the handle on the longitudinal axis at a predefined distance from the distal tip and is configured to output a signal indicative of a location of the probe. An alignment jig includes a connector configured to be fixed removably to the distal tip of the probe and three protrusions, which extend from the connector and are configured to contact a surface of a body of a patient at respective points, which are disposed in a plane perpendicular to the longitudinal axis when the connector is fixed to the distal tip of the probe.

摘要： Systems, methods, and devices for registering a 3D image of a patient with magnetic coordinates are disclosed. A tri-axial sensor (TAS) may be added to the 3D camera. The location and orientation of the TAS sensor may be determined based on the known magnetic fields that are applied by a magnetic field transmitter. The camera coordinate system may then be transferred to the magnetic coordinate system. After completing the registration of the 3D image with a CT image and the 3D image with the magnetic coordinates, the CT image may then be registered with the magnetic coordinates.
