ABSTRACT
The development of a multi-functional tumor combined therapeutic instrument based on improved PID algorithm is introduced. It is based on the theory of 1 + 1 = 3 or 1 + 1 + 1 > 3 curative effect enhancement by tumor combined therapy, and it can be used solely, or with the combination of chemotherapy or actinotheraphy or both for tumor hyperthermia. By adopting improved PID temperature control algorithm, the problem of temperature control precision reduction due to process characteristics changing with different heaters was solved, thus ensuring homogeneous and smooth radio frequency heating by different heaters to intracavity tumor foci. These experiments demonstrated that the new algorithm has strong adaptability and anti-disturbance capability, the equipment works stably and reliably, and it can control therapeutic temperature precisely (+/- 0.1 degree C), which indicates a good value in clinical application.
