According to the principle of mechanical oscillation proposed a new hardware system by ARMs3c2410 processing chip and liquid crystal display monitor.Describing thoroughly the principle, hardware circuit structure and related drivers. The result indicated that the system operation is convenient.This design is one kind of new operative technology for ultrasound contrast agent and it has the great innovation to the present preparation technology and realizes the commercialization hopefully.
