摘要：

A high-pass Body Birdcage Coil using cylindrical rods designed for a 1.5 T MRI system is presented. The operating resonant mode is investigated for optimized magnetic field homogeneity. The shielded Body Birdcage Coil is energized in the circularly polarized feed configuration. The input ports of the Body Birdcage Coil are matched (S-11 = S-22 = -19.7 dB) and isolated (S-21 = S-12 = -26.4 dB) at 64.3 MHz. The same analysis has been extended for human model loaded Body Birdcage Coil. A slight shift in the resonant frequency from 64.3 MHz to 63.5 MHz is observed for unloaded and human model loaded Birdcage Coil. The B-1(+) field distribution of human model loaded and unloaded Body Birdcage Coils are presented for dominant mode.
