Objective A breast disease diagnosis system based on the characteristics of near-infrared light is designed and implemented in this paper. Methods The system consists of light source,external control circuit of light source,capture card,near-infrared CCD camera,computer and the application software. The wavelength of 760nm and 850nm LED is selected as light source,external control circuit and capture card are used to implement sequential emitting of light source. Results The characteristic of this system is non-invasive,nonradiative and cheap. Conclusions This system is important in clinic research and application.
