Publication number: 20240153165Abstract: A method for correcting projection images in CT image reconstruction is provided. The method may include obtaining a plurality of projection images of a subject. Each of the plurality of projection images may correspond to one of the plurality of gantry angles. The method may further include correcting a first projection image of the plurality of projection images according to a process for generating a corrected projection image. The process may include performing, based on the first projection image and a second projection image of the plurality of projection images, a first correction on the first projection image to generate a preliminary corrected first projection image. The process may also include performing, based on at least part of the preliminary corrected first projection image, a second correction on the preliminary corrected first projection image to generate a corrected first projection image corresponding to the first gantry angle.Type: ApplicationFiled: January 15, 2024Publication date: May 9, 2024Applicant: SHANGHAI UNITED IMAGING HEALTHCARE CO., LTD.Inventors: Hongcheng YANG, Jianwei ZHU, Haining SUN, Jonathan MALTZ
