Compressed sensing (CS) is a technique that allows accurate reconstruction of images from a reduced set of acquired data. Here, we present a new method, which applies CS to only high-frequency subbands to maximally utilize the wavelet characteristics while minimizing reconstruction artifacts, and allowing easy incorporation of other rapid imaging techniques.
