Abstract
Apparatus and methods for fabricating scintillators for use in a CT systems are described. Adjacent scintillator elements are separated by gaps filled with a composition of white diffuse reflective material, a light absorber, and a castable polymer. The composition increases the strength of the signal to the photodiode by minimizing the amount of light that is lost by the scintillator elements. Additionally, the light absorber minimizes the amount of light transferred between adjacent scintillator elements to limit cross-talk. In addition, the outer edges of the scintillator may have a lower amount of light absorber to compensate for the light lost from the periphery.
