A SoC design for portable 2-dimension oximeter image system

In recent years, many studies of 2-D oxygen saturation distribution reconstruction have provided easy access to human brain activity regions. However, only a few research focus on the home health care system using this technique. In this paper, we proposed a portable, low cost and real-time distribution reconstruction system of oxygen saturation in 2-D to make diagnosis at home possible. The system has been implemented in hardware as an oxygen saturation processor and verified on Field Programmable Gate Array (FPGA). Furthermore, we also introduce an image post processing unit to enhance the reconstruction result. Finally, we show that our system can recognize the variation of oxygen saturation region with high precision in detection tissue.
