Finite number of secondaries and structured backgrounds and University of Arizona, Radiology Research Building 211, 1609 North Warren, Tucson, Arizona 85724 (Received 11 June 2002; accepted 16 October 2003; published 27 January 2004) The current paradigm for evaluating detectors in digital radiography relies on Fourier methods. Fourier methods rely on a shift-invariant and statistically stationary description of the imaging system. The theoretical justification for the use of Fourier methods is based on a uniform background fluence and an infinite detector. In practice, the background fluence is not uniform and detector size is finite. We study the effect of stochastic ...
