title: Modulation transfer function of fluorescent screens excited by x-rays.
abstract: A theoretically based calculation of the modulation transfer function is performed for phosphor screens excited by x-rays. It is assumed that the screens are of compact material so that scattering of the light generated can be neglected. The absorption of both x-rays and light in the phosphor material is taken into account.
