Research on Compressed Sensing in Ultrasound Imaging

The classic Nyquist sampling frequency usually causes the amount of sampled signal data to be too large, which is not conducive to storage and transmission. In order to reduce the amount of ultrasound imaging data and facilitate data storage, compressed sensing theory is used. Compressed sensing theory not only reduces the sampling frequency of RF signals, but also obtains a small amount of data. This article studies the basic theory of compressed sensing and its key technologies, and finally summarizes its application in other fields.
