A novel low power design scheme of medical image display system is proposed, based on the research of FPGA(Field Programmable Gate Array) low power design technology and medical image display system. Firstly, the power consumption of video and image processing system based on FPGA is analyzed. Then a method to reduce the dynamic power consumption of FPGA is proposed based on the tonal and spatial characteristics of medical images. Finally, taking radiographic medical images as an example, the signal flip ratio is reduced from 37.95% to 9.68% by using software statistics, which proves that the proposed scheme can effectively reduce the dynamic power consumption of FPGA.
