    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.

    Abstract: Embodiments of the present invention disclose a method for removing streaks from detector cells with performance difference, specifically a method for removing streaks from detector cells with performance difference and streaks caused by other reasons. The method comprises: estimating a projection on a detector cell with performance difference for each of one or more views; reconstructing one or more initial images with the estimated projection on the detector cell with performance difference for each view; estimating a projection error on the detector cell with performance difference for each view from the reconstructed one or more initial images having streaks; and reconstructing one or more output images with the estimated projection error on the detector cell with performance difference for each view to remove the streaks from the reconstructed one or more output images, improving quality of CT reconstructed images.

    Abstract: An image processing method comprises: identifying a weak edge comprising a plurality of weak edge pixels and a strong edge comprising a plurality of strong edge pixels in an input image; filtering at least a part of said input image to obtain a smoothed image, during which said weak edge in said input image is filtered with a first filter and said strong edge in said input image is filtered with a second filter having a smoothness less than that of said first filter; acquiring edge information of said input image based on said input image and said smoothed image; and generating an output image based on said edge information and said smoothed image. The present invention further relates to an image processing system and an imaging system.
