3D Alternating Direction TV-Based Cone-Beam CT Reconstruction with Efficient GPU Implementation

Figure 2

Digital phantom and the reconstructions for simulation data. The first column in the left is the phantom of 3D Moby mouse and the second, third, and fourth columns are the reconstructions of FDK, ASD-POCS, and the GPU accelerated new method. From the top row to the bottom row, there are slices of 𝑧=31, 𝑦=128, and 𝑥=128 in phantom and the reconstructions.
