Pre-sampled MTF for four incident beam angles (0°, 2.24°, 4.47° and 6.69°) using segmented scintilllators with tungsten septal walls. The results are shown for 10 – 40 mm thick BGO scintillators in (a), (c), (e) and (g) and CsI:T1 scintillators in (b), (d), (f) and (h). The simulation results are compared to the measured MTF from the conventional EPID.
