Abstract	Ultrasonic imaging technology is a remarkable new technology in modern nondestructive testing (NDT). However, at present, the main problem is that its resolution is lower, thereby directly affecting the application value of ultrasonic image. In this paper, the issue of how to improve the resolution of ultrasonic imaging is studied, the method of super-resolution techniques with applications to ultrasonic imaging is proposed. Firstly, the method uses micro-scanning imaging technology obtain low-resolution image sequences with sub-pixel displacement, then through the super-resolution image reconstruction methods obtains high-resolution ultrasound images. Based on the way of thinking, an immersion ultrasonic imaging experimental platform was established, the experimental platform has both ultrasound scan imaging functions, but also has the region of interest (ROI) for micro-scanning imaging functions. And some experiments are studied, the results showed: the method of super-resolution ultrasound imaging based on micro-scan is operational and original, and it is excellent reference material to improve the resolution of Ultrasonic imaging equipment.
