QSM
is relatively new biochemical and quantitative reconstruction method which
directly estimates the iron distribution. It needs a precision of separation of
local field from background field for measurement of accurate susceptibility
value. We introduced a novel method using non-regularized variable kernels
sophisticated harmonic artifact reduction for phase data (NR-VSHARP). The proposed
method utilized multiple kernel sizes and minimization of norm only inside mask
without any regularization parameter. NR-VSHARP enabled to estimate high accurate local field, compared with VSHARP. NR-VSHARP method provides high accurate local field map with saving cortical information.
