  2. 11. Radioluminescence : A simple model for fluorescent layers

    Author : Jan Lindström; Eva Lund; Michael Sandborg; Gudrun Alm-Carlsson; Linköpings universitet; []
    Keywords : Extrinsic efficiency; extinction factor; radioluminescence; modelling; Monte Carlo; optical attenuation; optimisation; particle size; phosphor; scintillator; MEDICINE; MEDICIN;

    Abstract : The aim of this thesis is to present a simple model for the radiation to light conversion processes in fluorescent layers as an aid in future developments and applications. Optimisation between sensitivity and spatial resolution for fluorescent layers in digital radiology is a delicate task where the extrinsic efficiency for various phosphors needs to be established for varying parameters.
