Title:
光カプラ複合物、光カプラ複合物を備えるX線検出器装置及び、X線検出器アセンブリを製造する方法
Document Type and Number:
Japanese Patent JP4669114
Kind Code:
B2
Abstract:
A technique is disclosed for providing a solid state X-ray detector for a CT imaging system with an optical coupler having a substantially reduced coefficient of thermal expansivity (CTE). In accordance therewith, a prespecified amount of a ceramic scintillator material, in powdered form, is mixed with the resin component of an optical coupling material, such as transparent epoxy, which has resin and hardener components. Air bubbles are removed from the powdered scintillator-resin mixture, and a prespecified amount of the hardener component of the optical coupling material is combined therewith to provide a powdered scintillator-optical coupler composite. The CTE of the composite is substantially less than the CTE of epoxy only. A monolithic block or body of the ceramic scintillator material is placed in close, spaced-apart relationship with a photodiode device, and the gap therebetween is filled with the reduced CTE optical coupler composite to eliminate air spaces therefrom.
