A novel RF resonator using microstrip transmission line for human body MRI at 3T

摘要：

　　A square-slots loaded (SSL) radio frequency (RF)resonator using microstrip transmission line (MTL) is designed for a human body 3T MRI.The SSL RF resonator shows greater penetrated RF magnetic fields near the center of the phantom than traditional RF resonators using MTL.A multichannel coil using SSL RF resonators was also simulated and provides good parallel excitation performance.In addition,RF shimming for homogenization can be effectively controlled by adjusting the inputs of eight resonators.Numerical results were obtained using a spherical phantom and a realistic human body model at 3T to calculate B+1 fields.
