A major challenge in QSM is inverting the acquired phase measurement to estimate the underlying susceptibility. Thresholded K-space division (TKD) is a straightforward technique to calculate the magnetic susceptibility distribution from a single orientation phase images. In this work, we propose to obtain an optimal inverse dipole kernel by using multiple thresholding to minimize the RMSE of the resultant susceptibility map against a susceptibility map
