This technology includes a method to reduce scanning time while retaining high image quality during MRI scans. A reconstructed image is rendered from a set of MRI data by first estimating an image with an area which does not contain artifacts or has an artifact with a relatively small magnitude. Corresponding data elements in the estimated image and a trial image are processed, for instance by multiplication, to generate an intermediate data set. The intermediate data set is transformed and minimized iteratively to generate a reconstructed image that is free or substantially free of artifacts. A sparsifying transformation may be applied to generate the reconstructed image.

Commercial Applications
To be used to reduce scanning time during MRI imaging.

Competitive Advantages
Current techniques require extended computational time and high memory usage.
