摘要

本文用有限元法建立了乳房消融术中微波辐射对周围组织的影响模型。提出了三种不同直径的天线设计，与周围组织进行模拟:脂肪组织、结缔组织和腺组织以及肿瘤组织。在研究天线的有效性时，应考虑乳房组织，以观察比吸收率(SAR)图的变化。该方法为微同轴天线的设计及其影响提供了参考。直径为0.95和1.3 mm的天线驻波比低于直径为2.30 mm的天线，因此直径较小的天线在深度为50 mm时的驻波比为1.5，响应效果更好。

Influence of the surrounding tissues in the radiation pattern of microcoaxial antenna for the treatment of breast tumors

This paper presents a model of microwave radiation into the surrounding tissues in the therapy of ablation of breast using the finite element method (FEM). Three designs of antennas with different diameters have been proposed to carry out simulations with the surrounding tissues: adipose tissue, connective and glandular tissue and tumor tissue. The tissues of the breast should be considered in the study of the effectiveness of the antennas to observe the change of patterns of the Specific Absortion Rate (SAR). The FEM provides information for designing of microcoaxial antennas and its effects. The antennas of 0.95 and 1.3 mm of diameter have a Standing Wave Ratio (SWR) lower than the antenna with a diameter of 2.30 mm, so the smaller diameter antennas have a better response to a depth of 50 mm with a SWR of 1.5.
