Abstract
Sensitometric response and modulation transfer function (MTF) measurements are used to scale noise power spectral (NPS) measurements to the exposure axis. The resulting value of noise equivalent quanta (NEQ) can be compared with the actual number of exposure quanta required to form the image (q ) ; the ratio yields the system detective quantum efficiency (DQE). Two systems used for mammography are studied.
