摘　　要：利用晶体振荡器设计稳定度很高的信号源,其输出由可编程放大器调节后,经过功率放大电路输出至线圈阵列,实现了对三种不同结构和性能的阵列线圈的驱动,使线圈阵列达到很好的磁场聚焦效果.The high frequency stability signal source array was designed using crystal oscillator, and its output was sent to the coil array via amplifiers which regulated the amplitude of signals. These circuits drove the coil array of three kinds of structure and performance in focused magnetic fields conductivity tomography system which performed the focus magnetic fields.

关 键 词：磁聚焦电导率成像 阵列信号源 聚焦线圈阵列
