  • Publication number: 20260029224
    Abstract: The present disclosure may be embodied as a probe for determining a position and pose of an anisotropic magnetic marker having a known size, shape, and magnetization. The probe has a substrate having a first side, a second side, a longitudinal axis, and a transverse axis. A first magnetic sensor is on the first side of the substrate. A second magnetic sensor is on the first side of the substrate and spaced apart from the first magnetic sensor along the longitudinal axis of the substrate and spaced apart from the first magnetic sensor along the transverse axis of the substrate. A third magnetic sensor is on the second side of the substrate. Each of the first magnetic sensor, the second magnetic sensor, and the third magnetic sensor is a multidimensional magnetic sensor. A processor is configured to determine a disposition of the magnetic marker in five degrees of freedom.

  • Patent number: 12521525
    Abstract: A magnetically-tracked catheter system having a catheter and a magnetic beacon. The catheter has a proximal end and a distal end. The catheter includes a first magnetic sensor disposed at (i.e., near) the distal end. The magnetic beacon is configured to be disposed external to an individual and in a target zone. An operator interface is in electronic communication with the first magnetic sensor. The catheter may further include a guide lumen (and/or other lumen or lumens) extending between the proximal end and the distal end and the configured for use with a guidewire. The catheter may include an occlusion member configured to occlude a vessel or other passage of an individual (e.g, respiratory tract, gastrointestinal tract, etc.).

  • Publication number: 20250387041
    Abstract: An exemplary method for detecting magnetic noise comprises: receiving a set of magnetic field gradient values obtained using a probe device; providing the set of magnetic field gradient values to a neural network to predict a marker state of a magnetic marker; providing the predicted marker state from the neural network to a magnetic field gradient prediction model to generate a predicted set of magnetic field gradient values; comparing the set of magnetic field gradient values obtained using the probe device with the set of predicted magnetic field gradient values; and providing a magnetic noise indicator depending on the comparison between the set of magnetic field gradient values obtained using the probe device and the set of predicted magnetic field gradient values.

  • Publication number: 20250386138
    Abstract: An exemplary method for providing feedback by a localization system comprises: obtaining location information of a marker, wherein the location information is generated by the localization system; generating a feedback signal comprising a plurality of audio tones, wherein each audio tone has a frequency different from the other audio tones of the plurality of audio tones, and wherein each audio tone is associated with a respective activation function of a plurality of activation functions, the respective activation function configured to modulate an amplitude of the respective audio tone based on the obtained location information of the marker; and providing the feedback signal to indicate the location information of the marker.
