摘要：
A medical device system includes an elongated body with a distal end that is configured and arranged for insertion into a patient. A housing is disposed in the distal end of the body. A rotatable magnet is disposed in the housing. At least one magnetic field winding is configured and arranged to generate a magnetic field at the location of the magnet. The magnetic field causes rotation of the magnet at a target frequency. An array of magnetic field sensors is disposed external to the patient. The magnetic field sensors are configured and arranged to sense the location and orientation of the magnet in relation to the array of magnetic field sensors.
