High-Frequency Subband Compressed Sensing MRI Using Quadruplet Sampling
PURPOSE: To presents and validates a new method that formalizes a direct link between k-space and wavelet domains to apply separate undersampling and reconstruction for high- and low-spatial-frequency k-space data. THEORY AND METHODS: High- and low-spatial-frequency regions are defined in k-space ba...
