US 2011/0255658 A1 · X-RAY CT APPARATUS AND X-RAY DETECTOR

Abstract

An X-ray detector of an X-ray CT apparatus has a plurality of collimators, a plurality of scintillators, a plurality of photodiodes and a light guide. The plurality of collimators collimate an X-ray. The plurality of scintillators respectively emit fluorescence based on the X-ray from the plurality of collimators. The plurality of photodiodes respectively convert the fluorescence from the plurality of scintillators into the electric signal. The light guide has such a shape as to guide the fluorescence emitted from the plurality of scintillators respectively to the plurality of photodiodes while focusing the fluorescence toward the plurality of photodiodes.
