Study On Control Methods Of Living Tissue Surface Temperature Under Radialization By Compound Light

Physiotherapy system of compound light is a part of an intelligent medical instrument treating cancer in the medical auxiliary system. It's necessary to choose the accurate temperature therapy project for the various disorders and the various positions of the body during the therapy. In the thesis, through researching on the control methods of living tissue surface temperature under the compound rays, an arithmetic of temperature controlled based on the fuzzy control theory is designed, which used specially in control of human body.In the thesis, firstly, it introduces what is compound light, and the bioeffects of all lights which form the compound light spectrum and how about their application in medical treatment. Secondly, it designs a method of contact measuring temperature through researching and comparing many kinds of measurement on temperature.For solving the difficulty in controlling temperature when examining the tissue of human which is special in certain aspect as a controlled object, a fuzzy controller and the control rules are designed, then the corresponding list for fuzzy control by fuzzy inference rules is determined. Subsequently, the rationality of the arithmetic about the controlling system was checked through simulating a first-order model with lag and inertia on this arithmetic by use of the fuzzy logic toolbox in Matlab.In this thesis, the hardware for the whole temperature controlling system is designed, and the controlling arithmetic by VB is programmed At last, the whole debugging from temperature acquisition to output control is accomplished by use of three tungsten halide lamps as the compound light source. Further more, after the experiment of controlling their temperature on living-tissue and decease-tissue finished, the corresponding varied temperature curves came into being. Referencing these curves, the controlling rules were...
