Abstract

We describe a new system for automated temperature control during laser hyperthermia. The system includes a PC with special software, in which a regulator is realized, infra red camera as a detector of temperature changes and laser with the 810 nm irradiation wavelength, which operates under PC control. The regulation was realized as a negative feedback adaptive control system, which tunes it self during the operating and do not need any prior information about the parameters of the irradiated tissue. The system was tested on different experimental models, the parameters of which varied in a wide range. The system showed a stable work with times of the transients about 60 seconds. The error of temperature stabilization was about ± 0.8 °C.
