Abstract: A head stabilization device or HFD includes a plurality of integrated markers. The HFD may be in the form of a skull clamp, vacuum bag, combinations thereof, or other supporting structure. The integrated markers include MRI markers detectable by an MRI scanner and fiducial markers detectable by a registration tool of a navigation system. The markers provide a reference point relative to an operation site in a patient for use in a navigation guided procedure and aid in registering or calibrating the location of the patient with captured images used in the navigation guided procedure.

Abstract: The disclosure relates to localizing medical devices within a body lumen, such as for identifying the location of, or navigating to, a target tissue. Embodiments include localizing a medical device extended out of a working channel of a delivery device. The medical device may include an imaging sensor, such as for mapping the body lumen. In many embodiments, a delivery device may include one or more sensors including a first sensor to interact with a tracking system to determine the location of the delivery device within a tracking volume and a second sensor to determine the location of the medical device relative to the delivery device. In many such embodiments, a controller may determine the location of the medical device in the tracking volume based on the location of the delivery device in the tracking volume and the location of the medical device with respect to the delivery device.

Abstract: A method for detecting a magnetic marker comprises generating a driving magnetic field comprising first and second frequencies and detecting a response magnetic field comprising first and second response components. The magnetic marker provides a non-linear response to the driving signal. A primary portion of the response components is generated by the magnetic marker, and a secondary portion of the response components is generated by a secondary magnetic source. The method comprises determining a driving factor representing a ratio of the frequencies in the driving signal; determining a correction factor corresponding to the secondary portion of the second response component, based on the first response component and the driving factor; determining a detection signal corresponding to the primary portion of the second response component, based on the second response component and the determined correction factor; and generating an output signal based on a strength of the detection signal.

Abstract: During both invasive and non-invasive treatments and therapies, health professionals need to accurately locate areas of interest. Inaccuracies may mean that not all the area is treated, or the treatment is incomplete. Electro-magnetic and RFID (Radio-Frequency Identification) markers have been developed, but these are bulky and prone to failure. For example, any inaccuracy may result in an incomplete resection or removal of the lesion, requiring additional treatments. A magnetic field probe 100, 101 is provided for determining an angular disposition 180, 190 of an implantable magnetic marker 200, the probe comprising: a first magnetic sensor 110 close to the distal end 160, and a second magnetic sensor 120, closer to a proximal end 165, configured to determine two or more magnetic field vectors of the marker 200; the probe being further configured: to define two or more marker detection zones 170, 171, 172, 173, 174, extending from the distal end 160; to determine the angular disposition 180, 190 to the implantable marker 200; and to determine whether the angular disposition 180, 190 substantially coincides with one of the two or more marker detection zones 170, 171, 172, 173, 174, thereby determining that the marker falls within the one marker detection zones. By defining two or more marker detection zones, and configuring the probe to determine whether the magnetic marker appears to be within the one marker detection zone, a simplified and intuitive decision algorithm is provided for indicating the disposition of the marker relative to the probe.
