A Novel Alternating Magnetic Field Measuring Device for Magnetic Induction Hyperthermia

摘要：

　　Alternating magnetic field is more and more widely used in medical devices.In experimental and clinical applications,the intensity,frequency and other parameters are usually the decisive factors,thus making the measurement of the magnetic field essential.An alternating magnetic field measuring device is designed,using three detection coils as the probes,a DSP chip is used for data acquisition and processing.The intensity,frequency and direction of the magnetic field can be measured.The intensity range of 18 Gauss to 78 Gauss and frequency range of 50 kHz to 800 kHz is measurable.The accuracy of both the measurement of magnetic flux density and the frequency is above 10%.
