Paper Abstract

Previously we used a simple 2-D model to evaluate the imaging performance of a digital radiographic system while varying input parameters such as transducer blur and signal size. We extend this work using a realistic phosphor simulation to explore the effect of the incident x-ray spectrum and the depth dependence of the point spread function and optical collection efficiency. Initially we investigate one Swank screen type representative of modern powder phosphor design. Images resulting from these simulations are used to get an estimate of the impact of these factors on lesion detectability. Results show that the simple 2-D model gives optimistic estimates of detectability.
