1. A magnetic resonance imaging (MRI) processor system comprising: memory configured to contain at least one data array representing an image; and at least one data processor configured to low-pass filter a data array representing said image in at least one of a k-space domain or image domain to produce a low-pass filtered data array; band-pass filter a data array representing said image in at least one of a k-space domain or image domain to produce a band-pass filtered data array; high-pass filter a data array representing said image in at least one of a k-space domain or image domain to produce a high-pass filtered data array; threshold and feather said band-pass filtered data array in the image domain to produce an edge mask data array; and multiply said edge mask data array with said high-pass filtered data array and add the result to said low-pass filtered data array in the image domain to produce a Gibbs' noise filtered image data array in the image domain.
