Claim One:
1. A method for mapping tissue magnetic susceptibility, the method comprising: acquiring magnetic resonance (MR) data, wherein the MR data correspond to a subject; determining a magnetic field based on the MR data; determining a relationship between the magnetic field at a given location to the magnetic susceptibility at that location; performing a convolution operation on the relationship between the magnetic field at the given location to the magnetic susceptibility at that location to obtain a noise property; estimating a magnetic susceptibility distribution of the subject based, at least in part, on the noise property, wherein estimating the susceptibility distribution of the subject comprises: determining a cost function corresponding to a susceptibility distribution, the magnetic field, a mask corresponding to a region of interest, and a Green's function; determining a susceptibility distribution that minimizes the cost function; and identifying the susceptibility distribution that minimizes the cost function as the estimated susceptibility distribution of the subject; and generating one or more images of the subject based on the estimated susceptibility distribution of the subject.
