We propose dynamically estimate, formulate and update the field components that are responsible for causing streaking artifact, as an additional regularization term for solving the QSM optimization problem. As a result, streaking artifacts arising from regions with highly disrupted local fields can be well suppressed, preventing them from spatially extending and affecting other regions of interest. The proposed method can maintain the accuracy of QSM results, and has the potential to be integrated into most QSM optimization algorithms.
