A spatial‐frequency dependent quantum accounting diagram and detective quantum efficiency model of signal and noise propagation in cascaded imaging systems

IA Cunningham, MS Westmore, A Fenster - Medical physics, 1994 - Wiley Online Library
The detective quantum efficiency (DQE) is a system parameter that can be used to accurately
describe image noise transfer characteristics through many imaging systems. A simpler …

A method for modulation transfer function determination from edge profiles with correction for finite‐element differentiation

IA Cunningham, A Fenster - Medical physics, 1987 - Wiley Online Library
In this paper we describe a technique for determining the modulation transfer function (MTF)
of an imaging system from an experimentally obtained edge profile. The technique includes …

Signal and noise in modulation transfer function determinations using the slit, wire, and edge techniques

IA Cunningham, BK Reid - Medical physics, 1992 - Wiley Online Library
The modulation transfer function (MTF) of an idealized imaging system can be determined
