Deblurring of Spiral Images in the Presence of Fat and Rapidly Varying B0

Eric Aboussouan¹, James G. Pipe¹

Spiral imaging with long acquisition windows is efficient but highly susceptible to off-resonance blurring artifacts. Iterative approaches to deblurring in the presence of fat and/or rapidly varying field are presented. Deblurring results of real and synthesized images are compared favorably to results of a common non-iterative deblurring approach.
