Reconstructed results of the probability method, where $\beta =0.9$, and the ROI is cropped in $[-3,3]$ along the z-axis. (a), (b) are the reconstructed PS. (c) normalized surface photon density calculated using APDD. (d)-(f) are the slices, which are perpendicular to the x, y, and z-axes at the probability core $(3.2,6.7,0.6)$ mm respectively.
