ABSTRACT:
A system and method to improve the quality of noisy computer tomography (CT) images that have been generated by a CT scanner running on low-power. The image noise is reduced by restoring crucial quantitative image information. The system does not fail when applied to sparsely-sampled and/or low-resolution projection data and is clinically viable in that it is a method that can be embodied in a practical, real-world system that can be used routinely in remote sites with limited access to electric power, and relies only on data that are available from standard medical CT scanners.
