At the moment great efforts are being made to develop non-invasive heating systems which produce controlled local or regional deep-body hyperthermia. Electromagnetic interference techniques (10-80 MHz) with several separated applicators or with multiple applicators can produce deep-body heating. In our institute a coaxial frequency-independent TEM radiofrequency/microwave applicator has been designed. This applicator can produce a theoretically optimal interference maximum in the centre of the body. The applicator is very simple to construct and inexpensive. To test the design with the equipment available, a scaled prototype of the TEM applicator has been developed. The prototype has a diameter of 20 cm and operates at 434 MHz. The applicator has been tested on several phantom materials. The measured absorbed power distributions are in good agreement with the calculated theoretical distributions. The theoretical calculations of the absorbed power distributions of a 10-80 MHz TEM deep-body applicator are very encouraging.
目前，人们正在大力研发非侵入性加热系统，该系统可产生可控的局部或区域性深部体温过高。利用多个分开的施加器或多个施加器的电磁干扰技术（10 - 80兆赫）能够产生深部体温过高。在我们研究所，已设计出一种与频率无关的同轴TEM射频/微波施加器。这种施加器理论上能在身体中央产生最佳干扰最大值。该施加器构造非常简单且成本低廉。为了用现有的设备测试该设计，已研制出TEM施加器的一个按比例缩小的原型。该原型直径为20厘米，工作频率为434兆赫。该施加器已在几种模拟人体组织的材料上进行了测试。测得的吸收功率分布与计算出的理论分布非常吻合。10 - 80兆赫TEM深部体温过高施加器吸收功率分布的理论计算结果非常令人鼓舞。
