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.

Method and system for reducing ringing artifacts in X-ray image

A method for reducing grid line artifacts in an X-ray image is disclosed, which includes acquiring an X-ray image by scanning an object, wherein the X-ray image comprises grid line artifacts; decomposing the X-ray image into a high frequency image and a low frequency image, wherein the high frequency image comprises the grid line artifacts; filtering the high frequency image to reduce the grid line artifacts in the high frequency image so as to obtain a filtered high frequency image; and combining the filtered high frequency image with the low frequency image to reconstruct an output image. A system adopting the above method is also disclosed.
