Improved Image Quality in a New CR System Using a BaFI: Eu Photostimulable Phosphor Plate

Abstract

The main component of a computed radiography (CR) system is its photostimulable phosphor and a unique fabrication of the plate to improve image quaity in the CR system. The use of a BaFI: Eu phosphor produced uniformly by crystal generation in solution provided exceptional performance, becauseiodide's high atomic weight furnishes a high x-ray absorption coefficient and, thus, low x-ray quantum noise. Furthermore, sharpeness is maintained because light scattering is minimized by a anti-scattering layer between the plate and its protective outer layer.
