Figure 3.

Presampled modulation transfer function (MTF) for the (a) BGO, (b) CsI-1, (c) CsI-2 and (d) CsI-3 prototype EPIDs. The results are shown for configurations with the black top reflector (blue lines) and the mirror top reflector (red dashed lines). The maximum estimated error in these MTF results is ∼3%. The green dot-dashed lines correspond to the MTF obtained from simulation of the various prototypes. The black crosses correspond to MTF results measured from the conventional EPID (adapted from data appearing in Ref. 2).
