Patent ID: 8692549

Claim:
A method for reconstructing images of an imaged subject from a parallel MRI acquisition, comprising: a. generating, for each response signal received by a respective RF reception coil, a complete dataset in k-space from a reduced k-space dataset of the respective response signal and associated weighting factors for the reduced k-space dataset; b. spatially transforming each complete k-space dataset generated to obtain an estimated reconstructed image for a respective RF reception coil, the estimated reconstructed image having a measure of sparsity; c. maximizing the sparsity of the estimated reconstructed images; d. repeating the generating and the spatially transforming steps using revised associated weighting factors obtained from each respective k-space dataset that results from the maximizing step; and e. combining the estimated reconstructed images for the respective RF reception coils to obtain a reconstructed image of the imaged subject.
