Abstract

The performance of a digital radiography system is characterized by the spatial resolution limit, the pixel contrast signal-to-noise ratio, the contrast detail curves, and the rendition of contrast signal. The importance and measurement of each of these characteristics are discussed. An equation for contrast detail curves based on noise analysis and threshold detection theory is derived to predict and interpret the low contrast performance of a digital radiography system. A phantom designed and constructed for law contrast performance is described.
