title: Energy dependence of photostimulable phosphor.
abstract: In this study, phantoms were used to illustrate the dependence of photostimulable phosphor's characteristic response on beam quality. These phantoms, consisting of sheets of acrylic and aluminum, represented an extremity, an abdomen, a skull and a chest. Images were taken with 50 to 65 kVp, 60 to 110 kVp, 65 to 80 kVp and 70 to 120 kVp, respectively. In general, the amount of resulting luminescence of the photostimulable phosphor per unit of air kerma (exposure) increased with kVp.
