Abstract:: Abstract: A magnetic resonance-guided thermal therapy device is designed for rehabilitation. The physiotherapy device consists of magnetothermal oscillator and control system. The magnetothermal oscillator provides 3 kinds of physical therapy factors, namely magnetism, oscillation and heat; and the control system achieves time setting and real-time monitoring of treatment temperature. The physiotherapy device can provide patients with more choices of magnetic field, treatment temperature, vibration massage and other parameters, thereby further maximizing the therapeutic effect. The magnetothermal oscillator of the physiotherapy device is tested and the results show that the temperature of the core-containing coil can be stabilized after being energized for 5 min and the temperature can be precisely controlled by setting the working power voltage. The results of this study confirm that the magnetic resonance-guided thermal therapy device has several advantages, including multi-magnetic field strength, independent temperature setting and two kinds of massage modes, which can well meet the needs of different patients.
