Abstract
A method is provided for evaluating an inhomogeneity in a magnetic polarizing field used to acquire an MRI image of a slice of a subject, at a point in the slice, the method comprising: acquiring data in a k-space for first and second k-space scans of the subject with a single application of a first MRI pulse sequence, wherein data acquisition for the second k-space scan is delayed with respect to data acquisition for the first k-space scan by a time delay; generating first and second spatial images from the first and second k-space scans; determining a phase difference between values of the first and second spatial images at the point; and evaluating the inhomogeneity at the point using the phase difference and the time delay.
