Fast conjugate phase image reconstruction based on a Chebyshev approximation to correct for B0 field inhomogeneity and concomitant gradients
2008
Magnetic Resonance in Medicine
Off-resonance effects can cause image blurring or artifacts in a number of fast imaging methods. Concomitant gradient (Maxwell) fields [1] and B0 inhomogeneity, including main field inhomogeneity and susceptibility-induced field variations, are two common sources of off-resonance effects. When B0 inhomogeneity and concomitant gradients are both present, correction of only one of them is insufficient and sometimes can increase blurring artifacts in some parts of the image. Since both B0 field
