Abstract
The present disclosure discloses a method for reducing ringing artifacts in an X-ray image, comprising: acquiring an X-ray image by scanning an object, wherein the X-ray image comprises grid line artifacts; applying a first bandwidth filter and a second bandwidth filter respectively to the X-ray image so as to obtain a filtered first image and a filtered second image, wherein the first bandwidth filter and the second bandwidth have different bandwidths; constructing a weighting map according to the X-ray image; and fusing the filtered first image and the filtered second image with the weighting map so as to obtain an output image. The present disclosure also discloses a system using the above method.
