Abstract
A method and system for removing butting or stitching artifacts from an image are disclosed. The system includes a locating module which is arranged to locate and identify at least one region in the image in which a butting artifact is present. A modeling module determines at least one model of a butting artifact as a function of electromagnetic absorption level, typically an x-ray absorption level, at the identified region. A subtraction module applies a subtraction algorithm to subtract the butting artifact from the image at the identified region based on the model of the butting artifact. The method may include applying linear and cubic interpolation algorithms to the butting artifact in the image to obtain respective linear and cubic interpolations of the butting artifact, or respective linear and cubic interpolation models.
