Resolution and noise in xeromammography.
The resolution and noise characteristics of the xeromammographic image are analyzed by means of a multistage model which considers the exposure, toner deposition, and toner transfer steps. A frequency-dependent theory of xeromammographic noise is developed and comparison is made with experimental results. Central to this theory is the concept of a toner electrode formed in the immediate vicinity of the Se layer. Comparison is also made between the imaging capabilities of xeromammography and screen/film systems. The paper concludes by addressing the question of normalization of the transfer function in an electrostatic system.
