(a) Quantum detection efficiency, escape efficiency (left vertical axis, black lines), and scintillator gain (right vertical axis, gray line) computed as a function of scintillator thickness. (b) Zero‐frequency P _K and integral of detector NNPS over the Nyquist frequency range (gray line) as a function of CsI thickness. (c) Examples of task functions [Eq. (14), normalized to peak values] for three feature sizes: 0.05 mm (solid black line), 0.1 mm (solid dark gray line), and 0.2 mm (solid light gray line). The tasks emphasize distinct frequency bands depending on the underlying feature size. [Color figure can be viewed at wileyonlinelibrary.com]
