Abstract

The invention discloses a rapid high-resolution ultrasonic imaging detection method. According to the method, by a super sub-sampling data imaging technology and a super-resolution technology, the problem of how to obtain relatively few sampling data and high-resolution ultrasonic imaging is solved under the condition of not increasing the cost of hardware equipment; and meanwhile, the imaging speed and quality are improved. According to the rapid high-resolution ultrasonic imaging detection method, the super sub-sampling imaging technology and the super-resolution technology are organically fused together and are applied to an ultrasonic detection system from compressed sensing and parse expansion theories as the starting point, so that the imaging speed and the imaging resolution are greatly improved on the present basis.

Description

technical field [0001] The invention relates to the fields of image processing and computer vision, and in particular to an ultrasonic imaging detection method based on compressed sensing and super-resolution technology. Background technique [0002] The spatial resolution of today's ultrasonic imaging systems is not high enough, and the imaging resolution is not as good as that of X-rays. In addition, ultrasonic imaging extracts useful information from a large amount of background noise. The image is seriously disturbed by noise, and the imaging quality is not ideal. However, in many cases, due to the influence of additive noise and probe point spread function in the process of ultrasonic transducer imaging, the ultrasonic image acquisition system can only obtain low-resolution images of degraded quality, and even limited by certain conditions, only A very small part of the complete data is collected for image reconstruction, which greatly limits the application of ultrason...
