Since QSM has been recently undergoing clinical trials and the MEDI toolbox plays an important role for this purpose, numerical implementation should be consistent in the sense of continuum limit. In this abstract, we point out a numerically inconsistent finite difference scheme that has been used in the MEDI toolbox and show that by replacing it with a consistent one it drastically improves image quality.
