Abstract: The mixed potential integral equation is applied to calculate the resonant properties ofhigh-temperature supercon ductors spiral coil in magnetic resonance imagine. The method is used to design the coil in 0.2Tand 0.5T magnetic resonance imagine system. The enhanced two-fluid model is used to obtain the radio frequency parameters of high-temperature superconductors. The simulated results are in good agreement with measured data. In addition, the coupling between two spiral coils is analyzed. It is important to phased array in nucleus magnetic resonance imagine.
