Real time imaging requires fast acquisition and low latency reconstruction algorithms. We propose the Gradient warp and UnderSampling Transform Operator (GUSTO) algorithm as a fast method for correction of aliasing and gradient warped images using a single matrix transformation. Proof of concept is shown with low resolution (64 x 64) phantom images.
