Claims (1)
- 被検体にX線を照射するX線源と、テーブル上の前記被検体を介して前記X線源と対向配置され、前記被検体を透過した透過X線を検出する2次元のX線検出器であって、前記被検体の体軸方向に沿って1次元のX線検出器が複数列配列された2次元のX線検出器と、を有するスキャナ本体と、
前記被検体のスキャノグラム像の撮影時に前記スキャナ本体と前記テーブルとを前記被検体の体軸方向に相対移動させるスキャナ・テーブル相対移動手段と、
前記2次元のX線検出器における前記体軸方向の両端に位置する1次元のX線検出器の検出データを比較し、その比較結果に基づいて、前記スキャナ・テーブル相対移動手段による前記スキャナ本体と前記テーブルとの相対的な移動に伴う撮影部位の変化に応じて前記X線源から前記被検体に照射する前記X線の曝射線量を変化させるX線制御手段と、
前記スキャノグラム像の撮影時に前記X線検出器から得られた被検体の体軸方向の検出データに基づいて前記スキャノグラム像を作成する画像処理手段と、
を備えたことを特徴とするX線CT装置。
