肿瘤联合治疗系统中温度控制的研究

Temperature Control in a Combined Therapeutic System for Tumor

肿瘤联合治疗系统是一种利用射频加热技术和热生物效应原理治疗人体肿瘤的医疗设备。它可以单独用于肿瘤热疗 ,也可以进行热化疗、热放疗或三联治疗。将改进的 PID算法运用于该系统的温度控制中 ,结合硬件检测和调节电路 ,解决了直接影响到治疗效果的温度精确控制这一关键问题。实验证明本系统工作稳定可靠 。

Tumor combined therapeutic system, a kind of medical instrument to restrain and kill tumor, is based on radio frequency heating technique and biological heating effect theory. It can be used solely or in combination with chemotherapy and actinotherapy for tumor hyperthermia. Combined with hardware measurement and adjustment, as well as application of the improved PID algorithm to the system of temperature control,the required accurate temperature control which directly influences the curative effect is realized. The experimental results presented in this paper demonstrated that the equipment works stably and reliably, and it is of good usefulness.
