摘要： Medical imaging techniques are mostly generated by human tissue echoes and received by the transducer which is converted to electrical signals, after amplification, extraction, processing, and then signals are converted by the digital scan converter for standard video signal, finally displayed by the display. We propose a scheme of real-time and multi resolution image acquisition system by FPGA control logic design based on the real-time data acquisition, beam forming, processing, acquisition and transmission to ARM embedded video signal processing system with high real-time requirements, so we choose FPGA and SRAM real-time acquisition system which can meet the above requirements in speed and capacity. According to the problems encountered in the process of high speed acquisition, a reasonable timing optimization and RTL level synthesis is designed. The experimental results show that the design and implementation of the image acquisition system is not only stable, but also significantly improve the overall performance of the image processing system.
