In recent years, many near-infrared systems are used to detect breast tumor. However, the large instrument size and unfriendly interface make them hard to be accessed by users. In this paper, we proposed a portable, wireless and user friendly breast imaging system for breast tumor early detection. The system is implemented on self-designed platform combined with front-end sensors, DOT chip by TSMC 90nm technology, and commercial display devices. Furthermore, we confirm the functionality of the system by phantom testing.
