title: A logit model for the modulation transfer function of screen-film systems.
abstract: An empirically derived logit function is proposed to describe the modulation transfer function of x-ray screen-film systems. Simple and exact weighted linear regression analyses are performed to characterize the function and to describe the data within experimental accuracy. Calculations comparing the proposed function and the complementary error function (probit) representations of the modulation transfer function are given and discussed.
