| description | PROBLEM TO BE SOLVED: To provide an X-ray detector which can protect a circuit and the like formed on a photodiode alley without causing output fluctuation due to X-ray focus movement: and to provide an X-ray computer tomographic apparatus including the X-ray detector.SOLUTION: An X-ray detector includes a plurality of light receiving bands and collimator plates. The collimator plates are arranged and shaped so that the width of one end of the light receiving band side of each of the collimator plates is narrower than a gap facing the one end and a projection region where the collimator plate is projected by X-rays is wider than the projection region where the other end at the X-ray tube side of the collimator plate is projected by the X-rays.SELECTED DRAWING: Figure 2
【課題】Ｘ線焦点移動による出力変動を生じることなく、フォトダイオードアレイに形成される回路等を保護することができるＸ線検出器および当該Ｘ線検出器を備えるＸ線コンピュータ断層撮影装置を提供する。【解決手段】実施形態によれば、Ｘ線検出器は、複数の受光帯と、コリメータ板とを備える。コリメータ板は、コリメータ板の受光帯側の一端の幅が当該一端に対向する間隙の幅より狭く、かつＸ線によりコリメータ板を投影した投影領域がＸ線によりコリメータ板のＸ線管側の他端を投影した投影領域より広くなる配置および形状とする。【選択図】 図２ |
