Abstract


This paper put forward and realized based on embedded processor in a portable ultrasonic diagnostic instrument terminal system, this type of ultrasonic instrument is mainly used for field medical aid. The terminal system based on ARM FPGA architecture, the embedded Linux operating system and MiniGUI graphical interfaces. This design makes the portable ultrasonic instrument structure undergone a fundamental change, the previous based on FPGA, compared to the ultrasonic function more complete, image more clear, more rich interface; Based on PC with ultrasonic, compared with similar function, but cost, power consumption and volume are very lower. This article through to the ARM and FPGA interface of thorough research, a very good solution to solve the ultrasonic data transmission and high resolution ultrasound dynamic image real-time display problems. In the Linux operating system, using the processes between the network communication mechanism, realize the ultrasonic image and interface between the seamless connection. At the same time in the familiar with master MiniGUI structure, based on the implementation of a complete ultrasonic operation interface design. The final debugging results show that the two sides of hardware and software, this design can reach the portable ultrasonic instrument technology target, has the very good application prospect.
