Magnetic flexible catheter tracking system and method using digital magnetometers

Abstract

A method for magnetic tracking of a flexible catheter device or another flexible elongated device, the method comprising: receiving by a host server a plurality of sensed values of a local magnetic field, sensed by a respective plurality of sensors, wherein the host server is optionally included in a controller of the sensors, the sensors are located along a flexible tube of a device, wherein the sensed values are at least partially due to at least one alternating magnetic field generated by at least one magnetic field generator, the source amplitude and frequency of each generated magnetic field are given to the host server; and calculating by the host server, based on the sensed magnetic field values and the given source amplitude and frequency of each generated magnetic field, a localization of the flexible tube.
