Abstract :
This paper concerns reconstruction of MR images from raw, nonuniformly sampled k-space data. The exposed methods are (1) gridding, which resamples to a uniform rectangular grid and works well in the absence of undersampling; and (2) Bayesian estimation, which can accommodate undersampling
