A magnetic field generator assembly is configured to be associated with a table supporting a body. The magnetic field generator comprises a plurality of magnetic field transmitters, each comprising interlacing layers of conductive material, configured to provide increased magnetic strength and minimal fluoroscopic occlusion. The interlacing layers of conductive material can be arranged in rectangular spiral formations.

Multi-layer flat coil magnetic transmitters

A method for detecting and correcting for magnetic field distortions within a magnetic field used for medical magnetic localization systems may include a first set of one or more signals is indicative of the magnetic field sensed by each of the sensor coils within the metal distortion detection fixture at a first time received from the metal distortion detection fixture. A first magnitude value of the combined signals is determined. A second set of one or more signals is indicative of the magnetic field sensed by each of the sensor coils at a second time is received and a second magnitude value of the combined signals is determined. A magnetic shift in the magnetic field between the first and second magnitude values is determined. The magnetic shift is compared to a threshold shift amount indicative of a magnetic distortion in the magnetic field.

Magnetic field distortion detection and correction in a magnetic localization system

A registration fixture is configured for use with a medical imaging system. The registration fixture comprises a rigid internal structure comprising a plurality of fiducial markers arranged in a predefined pattern. The registration fixture further comprises a housing configured to surround the rigid internal structure. The registration fixture is configured to be mounted on a patient table.

Mechanical design considerations for table-mounted device used as a sub-assembly in a magnetic tracking system working in conjunction with an X-ray imaging system

Aspects of the present disclosure are directed to apparatuses for generating a magnetic field for tracking of a target object. Such an apparatus may include a localized magnetic field transmitter that generates a magnetic field and exhibits minimal X-ray absorption when used in proximity to a fluoroscopic imaging system, for example.

Localized magnetic field transmitter

Various embodiments of the present disclosure identify and correct for magnetic field distortions within a magnetic field for localization of a medical device within a patient. Such magnetic field distortions, often associated with the intrusion of a metallic object into the magnetic field, may cause an unacceptable level of localization error which aspects of the present disclosure correct for.

Aspects of the present disclosure are directed to systems, apparatuses, and methods for detecting and correcting for magnetic field distortions within a magnetic field used for medical magnetic localization systems.
