Fig. 17.
Numerical simulation results of the FORBID head phantom. (a) is the ground truth. (b) and (c) are the reconstruction results from GPU-BL and CPU-32, respectively. The display window for on the first row images is [1.0,1.2]. (d) is the differences between (b) and (c) in a display window [−0.005,0.005]. (e) and (f) are the reconstruction errors of (b) and (c) with respect to (a) in a display window [−0.02,0.02].
