Sensitivity Encoded Image Reconstruction Using Direct Regularization

Parallel imaging technique has been proposed to utilize simultaneous data acquisition from multiple RF receivers to improve the spatiotemporal resolution of MRI (Sodickson and Manning 1997; Pruessmann, Weiger et al. 1999). Mathematically, the formation and the reconstruction of the parallel MRI, including image domain and k-space domain variants, have been formulated as linear equation (Sodickson and McKenzie 2001). Thus matrix inversion is a critical process in reconstructing a full-FOV image. Previously we showed that using the prio
