Chinese Journal of Magnetic Resonance, Vol 35, Iss 1, Pp 31-39 (2018)
Both compressed sensing (CS) and parallel imaging (PI) can be used to accelerate magnetic resonance imaging (MRI) by under-sampling the k space data. Several methods combining CS and PI have been proposed to further improve the scanning speed. In thi
