Abstract
An imaging system includes a computer programmed to reconstruct original CT projection data, estimate noise in image space, forward project the image noise estimate to generate an initial projection noise estimate, modify the initial projection noise estimate using a statistical property of noise in projection space, remove noise in the original CT projection data by subtracting the modified noise estimate therefrom to generate noise-removed projection data, and reconstruct a final image based on the noise-removed projection data.
