Abstract:
Objective To design a novel medical infrared real-time imaging system based on uncooled focal plane assembly(UFPA).Methods The hardware includes optics,infrared detector,thermal image acquisition & pre-treatment circuit and portable computer.The software includes original image data acquisition and correction module,image real-time treatment and display module,pseudo-color treatment module and image storage and off-line analysis module.Two points revising method was proposed aiming at the unevenness of pixel.Results Dispensing with refrigeration,the resolution of medical infrared real-time imaging system was 0.1℃.The measuring temperature ranged from-20℃ to 100℃ with ambient temperature ranging from 0℃～40℃.The real-time imaging speed was 25 frame/s.Conclusion The medical infrared real-time imaging system can form infrared image in real-time,which meets the requirement of clinical application.
