Abstract:
The current invention is generally related to an image processing method and system for substantially reducing ring artifacts. Using the attenuation data, the ring artifacts are substantially prevented based upon two-step process, and the second ring artifact reduction step removes the undesirable rings based upon previously determined statistical data including mean and standard deviation.
