Splitting with Near-Circulant Linear Systems: Applications to Total Variation CT and PET

Ernest K. Ryu, Seyoon Ko, Joong-Ho Won

Many imaging problems, such as total variation reconstruction of X-ray computed tomography (CT) and positron-emission tomography (PET), are solved via a convex optimization problem…
