Structure for collimated scintillation detectors useful in tomography
Creators
Description
Structures for containing and supporting scintillator bodies are disclosed in which the optical output of the scintillator body is channeled by light reflective means to photoelectrically responsive devices mounted on the top and bottom of the detector array. In accordance with one embodiment of the invention, the internal surfaces of the collimating array are coated with either a diffuse or specular reflective coating. In accordance with another embodiment of the invention, the photoelectrically responsive transducers are located at the top and bottom of the array rather than at the rear. In accordance with another embodiment of the invention, reflective light channeling wedges are provided to improve spacing requirements for the photoelectrically responsive transducers. The scintillator structures of the present invention provide superior optical coupling to photoelectrically responsive devices
