Abstract

A microwave heating system, designed to improve temperature uniformity in heated tissue, is described. The system employs parallel-opposed waveguide applicators, operating in the TE10 mode at 2450 MHz with the tissue to be heated (i.e. mouse intestine) immersed in a liquid which is both biologically compatible with and dielectrically similar to the tissue. The liquid improves the microwave coupling and avoids shape and size dependent absorption characteristics of the irregularly shaped tissue. Also, by maintaining this liquid at a suitable temperature with respect to that required in the tissue, the thermal losses and hence temperature gradients in the tissue are reduced compared with heating in hot liquid alone.

摘要

本文描述了一种旨在提高被加热组织温度均匀性的微波加热系统。该系统采用平行对置的波导辐射器，在2450 MHz频率下以TE10模式运行，待加热的组织（即小鼠肠道）浸没在一种与组织具有生物相容性且介电特性相似的液体中。这种液体改善了微波耦合，避免了不规则形状组织因形状和尺寸而产生的吸收特性。此外，通过将这种液体维持在相对于组织所需温度合适的温度，与仅在热液体中加热相比，组织中的热损失以及由此产生的温度梯度都降低了。
