Slices corresponding to the plane z = 6.0-mm (top row: a-c) and the plane z = 4.5-mm (bottom row: d-f) through the 3D-images of the six-tube phantom reconstructed from the 144-view data by use of the PLS-Q algorithm with varying regularization parameter α : (a), (d) α = 0; (b), (e) α = 1.0 × 103; and (c), (f) α = 5.0 × 103; All images are of size 19.8 × 19.8-mm2. The ranges of the grayscale windows were determined by the minimum and the maximum values in each image.
