A computer-implemented method for correcting artifacts within CT images of a subject includes providing iteratively correcting a CT volumetric image with a high-contrast mask by overpainting the high-contrast mask within CT volumetric image set by evaluating a model function and updating the CT projections to reflect the overpainting using a gradient descent based on previous overpainted CT projections, back-projecting the corrected CT projections to produce a corrected volumetric image set, and comparing the corrected CT volumetric image set against a previous corrected CT volumetric image set until convergence. The original voxels overpainted by the high-contrast mask are re-inserted into the converged CT volumetric image to produce the final CT volumetric image set.

Methods of image reconstruction to reduce artifacts in rapid CBCT scans

Among the various aspects of the present disclosure is the provision of methods and systems for real-time 3D MRI that combines dynamic keyhole data sharing with super-resolution imaging methods to improve real-time 3D MR images in the presence of motion.
