Fast automatic debluring with a linear map

Meyer C, Chen W

Field inhomogeneity can cause image blurring for non-2DFT acquisitions. We propose a fast automatic off-resonance correction method, which performs linear correction without acquiring extra field map datasets. Our method needs only about two times the computation time of image reconstruction by gridding, and it is likely more robust than pixel-by-pixel based automatic methods. Our method can be a useful technique for fast deblurring when field map based off-resonance correction methods are undesirable or unreliable.
