摘要： 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.

摘要： A magnetic localization system including a magnetic field generator that generates an alternating magnetic field with a maintained frequency; and a receiver comprising: a DC magnetometer to sense a local magnetic field, at least in part due to the generated magnetic field; and at least one processor that calculates a six-degrees-of-freedom (6DOF) position and orientation of the receiver relative to the generator, based on the sensed magnetic field and the maintained frequency, and optionally based on the momentary phase of the generated field. Optionally, the generator includes an actuator that applies a rotational motion; at least one magnet rotating about a first axis by the actuator; a magnetometer to sense a momentary rotation phase of the at least one magnet; and a controller to maintain a desired rotation frequency of the at least one magnet. Optionally, the generator communicates the maintained rotation frequency and optionally the sensed momentary phase.
