Abstract

Various systems and methods are provided for MAR in CT images. A corrupted CT image, of a region of interest (ROI) of a subject, including artifacts caused by a metal object in the subject may be acquired. A corrupted sinogram including a corrupted region of corrupted data caused by the metal object and an uncorrupted region of uncorrupted data may be generated. A mask sinogram that delineates the corrupted region of the corrupted data may be generated. A corrected sinogram including the uncorrupted region of the uncorrupted data and an inpainted region of inpainted data corresponding to the corrupted region may be generated using a denoising diffusion probabilistic model, the corrupted sinogram, and the mask sinogram. A corrected CT image, of the ROI of the subject, that includes reduced artifacts relative to the artifacts in the corrupted CT image may be generated based on the corrected sinogram.
