摘要： In one example of an embodiment of the invention, a method to correct for ring artifacts in an image is disclosed. A first Cartesian image is reconstructed based on data received from an imaging device, and the first Cartesian image is transformed into a first polar image. A first low-pass filter is applied to the first polar image, in the radial dimension, to form a second polar image, and the second polar image is subtracted from the first polar image to generate a third polar image. A second low-pass filter is applied to the third polar image, in an angular dimension, to form a fourth polar image, and the fourth polar image is transformed to Cartesian coordinates to form a second Cartesian image. The first Cartesian image is corrected based, at least in part, on the second Cartesian image.
