This presentation provides an overview of electromagnetic heating technology that has proven useful in clinical applications of hyperthermia therapy for cancer. Several RF and microwave antenna designs are illustrated which highlight the evolution of technology from simple waveguide antennas to spatially and temporally adjustable multiple antenna phased arrays for deep heating, conformal arrays for superficial heating, and compatible approaches for radiometric and magnetic resonance image based non-invasive thermal monitoring. Examples of heating capabilities for several recently developed applicators demonstrate highly adjustable power deposition that has not been possible in the past.
本报告概述了电磁加热技术，该技术已被证明在癌症热疗的临床应用中很有用。文中展示了几种射频和微波天线设计，这些设计突出了技术的发展历程，从简单的波导天线发展到用于深部加热的时空可调多天线相控阵、用于浅表加热的共形阵列，以及用于基于辐射测量和磁共振成像的非侵入性热监测的兼容方法。几个最近开发的施药器的加热能力示例表明，其功率沉积具有高度可调性，这在过去是无法实现的。
