Abstract

The use of interstitial microwave antenna array hyperthermia (IMAAH) as a treatment for cancer, in conjunction with radiation therapy and chemotherapy, has been investigated widely. The heating pattern produced by a coherently phased 915 MHz asymmetric antenna array displays the maximum power deposition in the array center. This paper investigates the effect of variable insertion depth between antennas of an array on the heating patterns produced. The "study" of this heating behavior demonstrates a similar effect to that of the variably phased arrays, showing a shift of the heating peak towards the periphery of the tumor, offering a more simple method for the clinical treatment of such tumors.

摘要

间质微波天线阵列热疗（IMAAH）作为一种癌症治疗方法，与放射治疗和化疗联合使用，已得到广泛研究。相干相控915 MHz不对称天线阵列产生的加热模式显示，最大功率沉积在阵列中心。本文研究了阵列天线之间可变插入深度对所产生加热模式的影响。对这种加热行为的“研究”表明，其效果与可变相控阵列相似，加热峰值向肿瘤周边移动，为这类肿瘤的临床治疗提供了一种更简单的方法。
