Abstract

A method for reducing a linear artifact in a medical image. The method includes identifying, in the medical image, a region occupied by the linear artifact and isolating, in the region, a signal intensity component attributed to the linear artifact from an overall signal intensity of the region. The method further includes obtaining a corrected signal intensity by subtracting, in the region, the signal intensity component attributed to the linear artifact from the overall signal intensity of the region, and, after obtaining the corrected signal intensity, correcting a contrast in the region to match the contrast in surrounding regions.
