14. A method for detecting radiation in a radiation detection system including a radiation source, a detector array configured to detect attenuated radiation from the radiation source passing through an object between the radiation source and the detector array, the detector array including a photosensor array and an array of scintillators optically coupled to the photosensor array and a thermoplastically encased reflective film between and in front of the scintillators of the scintillator array, said method comprising the steps of:
-
emitting radiation directed at the object;
reflecting light from the thermoplastic reflective film and transmitting light generated by the scintillators to the photosensor array; and
generating an electrical output detection signal representative of light impacting the photosensor.
