Research of remote noninvasive temperature monitoring system based on infrared

Thermotherapy has good curative effect on many diseases and has been widely applied in clinical. However, the temperature of target tissue should be monitored as it would increase in hyperthermia and effect treatment. In the paper, we proposed a 3D temperature measurement system based on far-infrared that can remote monitor hyperthermia patient´s tissue temperature in real-time in order to help surgeons making treatment plans. The system could first obtain the tissue surface position and temperature by 3D imaging. And then the temperature within the tissue could be estimated according to the principle of biological heat transfer and noninvasive temperature measurement was realized preliminarily. Finally, the feasibility of the system was discussed and verified in experiment by comparing with internal temperature curve obtained by a multichannel temperature measurement system.
