To investigate the relationship between the quality factor of a receiving coil made from specified superconducting material and resonant frequency in MRI system,a simulation model was developed using the HF software Ansoft HFSS and according to the size of the experimental setup of Bi2223/Ag superconducting receiving coil.Analyzing the frequency characteristics of resonance loop,it was found that the simulation results are basically in accord with the experimental results.The relationships between the quality factor of superconducting receiving coil and different resonant frequencies were obtained by adjusting the resonance capacitance of resonance loop to change its resonant frequency.The results indicated that only if the RF receiving coil is made from superconducting material and operating at low frequency,the signal noise ratio(SNR) in MRI system can be effectively improved.
