绝缘天线的填隙式阵列为深部肿瘤的微波热疗带来了希望。现有用来预测这些天线电磁能沉积的分析技术只有在天线阵列周围是均匀传导介质的情况下才有效。因为肿瘤及其宿主组织的电特性可能有所不同,所以在建立填隙式天线模型的过程中,有必要在计算电磁场分布及其能量沉积模式时考虑这种电特性变化和肿瘤几何形状的影响。本文阐述了一种在一填隙式天线阵列电磁场作用下的任意形状肿瘤的三维模型,它可用来预测非均匀肿瘤组织介质中的电磁能沉积。作者已求出了描述
The interstitial array of insulated antennas offers hope for microwave hyperthermia in deep tumors. Existing analysis techniques used to predict the electromagnetic energy deposition of these antennas are only effective if the antenna array is uniformly conductive around the media. Because the electrical properties of the tumor and its host tissue may vary, it is necessary to account for this change in electrical properties and tumor geometry in the calculation of the electromagnetic field distribution and its energy deposition pattern in establishing the interstitial antenna model . This article describes a three-dimensional model of an arbitrarily shaped tumor under the influence of an interstitial antenna array electromagnetic field, which can be used to predict the electromagnetic energy deposition in non-uniform tumor tissue media.
