High Performance 3D PET Reconstruction Using Spherical Basis Functions on a Polar Grid
Figure 4
CV measured in the hot (red), warm (green), and cold (blue) ROI for the CPU-single-core implementation (), the CPU-multicore implementation (+), and the GPU implementation () for 300 iterations measured every 10 iterations (a). The differences in between the CPU-single-core/CPU-multicore (red) and CPU-single-core/GPU (blue) implementations for the hot (), warm (+), and cold () ROI are shown in (b).
