摘要

尽管微波治疗仪已在临床上应用多年,但是仍然存在无法适应人体负载变化多端的问题。当负载发生变化时,天线反射可能会很大,从而导致负载吸收到的功率小于标称功率,影响治疗效果,反射增大还可能通过负载牵引原理导致磁控管输出不稳定,并可能导致漏波增大,对人体造成潜在危害。本文设计制作了一个基于STM32微控制器的微波源自动控制系统,以及带有微波剂量监测的微波辐射天线,当负载得不到足够功率时,自动控制系统会给出提示。经实验测试,微波源控制系统工作运行正常、稳定,微波辐射天线反馈回来的功率能反映出实际辐射功率。
Although having been applied in clinic for many years, microwave therapeutic instrument still can't match of human body due to the changeable loads. When loads change, reflection of the antenna may be very large, and it will lead to the power absorbed by the load less than the nominal power and affect the effect of treatment. Due to load traction, the increase of reflection may lead to the unstability of magnetron output and the high microwave leakage that are potential risks to human body. In this paper, a microwave source automatic control system based on STM32 microcontroller and microwave radiation antenna with microwave dose monitoring are designed and measured. Experiments show that the microwave source control system works normally and stably, and the power that the microwave radiation antenna feedback can reflect the actual radiation power.
