Figure 3From: Improved total variation minimization method for few-view computed tomography image reconstruction A comparison study on the reconstructed images by ASD-POCS and API-TV algorithms respectively, each of which took 60 additive noisy cone-beam projections (about 10% white noise) and 50 iterations: (a) the reconstructed image by the ASD-POCS algorithm, and (b) the reconstructed image by the proposed API-TV algorithm. The grey scale display range is [0.8, 1.2].Back to article page
