Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Quantitative susceptibility mapping (QSM) reconstruction is a ll-known ill-posed problem. Various regularization techniques have been proposed for solving this problem. , a rapid method is proposed that uses l 0  norm minimization in a gradient domain. Because l 0  minimization is an NP-hard problem, a special alternating optimization strategy is employed to simplify the reconstruction algorithm. The proposed algorithm uses only simple point-wise multiplications and thresholding operations, and significantly speeds up the calculation. Both numerical simulations and in vivo experiments demonstrate that the proposed method can reconstruct susceptibility fast and accurately. Because morphology information ighted methods have achieved considerable success in QSM,  performed a quantitative comparison with some typical ighted methods, such as MEDI (morphology enabled dipole inversion), iLSQR (improved least squares algorithm), and   wl 1       w    l    1           (ighted   l 1        l    1          norm minimization). The reconstructed results show that the proposed method can provide accurate results with a satisfactory speed.
