[Temperature control in a combined therapeutic system for tumor]

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.
