    • System (10) for irradiating living bodies or portions thereof, using electromagnetic radiation. A source or generator (18) provides electromagnetic energy at a selected frequency within an operational band width, via a coaxial cable (22) to an applicator (20) for radiation into living tissue (12). The source (18), cable (22), and applicator (20) each have a characteristic impedance approximately equal to the average impedance of the living tissue (12) over a broad frequency band, thus enabling efficient operation of the apparatus (10) without using auxiliary impedance matching devices. The applicator (20) is of a waveguide transmission line type (96) enabling efficient transmission and radiation of the electromagnetic energy and further incorporates means (58) for cooling surface portions (24) of the living tissue (12) during radiation thereof. Selective dielectric loading (114, 116, 118, 120 + 122) is provided. A feedback control system (28) including temperature sensors (34, 36 + 38) placed onto or into the tissue (12) enables the control of tissue surface and subsurface temperatures within a preselected range by adjusting the power level of the generator (18).
    • 用于使用电磁辐射照射活体或其部分的系统(10)。 源或发生器(18)通过同轴电缆(22)将工作带宽内的选定频率的电磁能量提供给施加器(20),用于辐射进入生物体组织(12)。 源极(18),电缆(22)和施加器(20)各自具有近似等于在宽频带上的生物体组织(12)的平均阻抗的特性阻抗,从而使得装置(10)能够有效地操作, 不使用辅助阻抗匹配装置。 施加器(20)具有能够有效地传输和辐射电磁能的波导传输线类型(96),并且还包括用于在其辐射期间冷却活组织(12)的表面部分(24)的装置(58)。 提供选择性介电负载(114,116,118,120 + 122)。 包括放置在组织(12)上或组织(12)上的温度传感器(34,36 + 38)的反馈控制系统(28)使得能够通过调节发电机(18)的功率水平来控制预选范围内的组织表面和地下温度, 。
