Scatter profiles obtained by the beam stop measurement and various simulations. Simulated scatter including contributions from the aluminum filter, the plastic cover, and CsI crystal of the detector demonstrated the similar shape as the measured scatter. The simulated scatter after the background scatter subtraction agrees well with the scatter simulated from the phantom-only except near the edges of the phantom.
