Patent ID: 7064334

Claim:
A CT detector comprising: a plurality of scintillators arranged in an array to receive x-rays and output light in response to the reception of x-rays; a plurality of reflector elements with a single reflector element disposed between adjacent scintillators; a plurality of light detection elements arranged in an array to output electrical signals in response to light detected from the plurality of scintillators; and an optical coupler to secure the plurality of scintillators to the plurality of light detection elements, the optical coupler having a plurality of air cavities defined by cavity plates disposed between the plurality of scintillators and the plurality of light detection elements such that each reflector element is aligned with a corresponding cavity plate and has a width substantially equal to that of the corresponding cavity plate, wherein the optical coupler includes a gridded screen defining a plurality of light transmission cavities between the plurality of scintillators and the plurality of light detection elements.
