Abstract

Examples of systems and methods for providing alternating magnetic field therapy are provided. One example method includes the steps of positioning a target proximate to a first end of an alternating magnetic field (AMF) head, the AMF head comprising an electrical coil and a ferromagnetic core, the electrical coil having a substantially circular cross-section that is substantially centered on a first axis, the AMF head having the first end corresponding to a first end of the coil and a second end corresponding to a second end of the coil; generating and transmitting an alternating current (AC) signal to the AMF head; determining a temperature of the target based on a sensor signal from a temperature sensor; in response to determining the temperature, modifying the AC signal based on a difference between the temperature and a predetermined target temperature.

Dependent claims

A system comprising:

an alternating magnetic field (AMF) head, the AMF head comprising an electrical coil and a ferromagnetic core, the electrical coil having a plurality of windings defining an interior region, the ferromagnetic core at least partially disposed within interior region defined by the electrical coil, the AMF head having a first end corresponding to a first end of the electrical coil and a second end corresponding to a second end of the electrical coil;
an AMF generator coupled to the AMF head, the AMF generator configured to generate an alternating current (AC) signal and transmit the AC signal to the electrical coil of the AMF head;
a temperature sensor configured to sense a temperature of a target positioned proximate to the first end of the AMF head, the temperature sensor positioned external to a patient's body and comprises an infrared sensor, an infrared camera, or a visible light camera;
and
a processor in communication with the AMF generator and the temperature sensor, the processor configured to:
iteratively:
detect a rate of change of temperature of the target at a first frequency,
store the rate of change of temperature associated with th first frequency,
change the frequency to a second frequency,
detect a rate of change of temperature of the target at the second frequency, and
store the rate of change of temperature associated with the second frequency;
determine a resonant frequency of the target based on the stored rates of change of temperature;
and
generate and transmit a control signal to the AMF generator based on the resonant frequency, the control signal configured to cause the AMF generator to output the AC signal with a first magnitude or at a first frequency to project an AMF onto the target,
receive a sensor signal from the temperature sensor, the sensor signal indicating the temperature of the target,
modify the control signal to cause the AMF generator to change the first magnitude to a second magnitude, or to change the first frequency to a second frequency, based on a difference between the sensed temperature and a predetermined target temperature, and
transmit the modified control signal to the AMF generator to project a modified AMF onto the target.
