| Zusammenfassung: | To provide a dental X-ray imaging apparatus capable of obtaining an imaging angle in which the shadow disorder is hard to occur.SOLUTION: An imaging unit lifting/lowering mechanism lifts and lowers the X-ray generator 10 in an opposite direction each other in the direction intersecting with the dentition arrangement direction and simultaneously a beam shaping machine 22 changes an angle of the X-ray slit beam B so that an irradiation position and the angle of the X-ray slit beam B to an imaging target area OL may be changed, and whereby an imaging mechanism 3 performs tomography of the imaging target area OL.SELECTED DRAWING: Figure 11
【課題】歯科用Ｘ線撮影装置において、陰影障害の発生しにくい撮影角度を得られるようにする。【解決手段】撮影対象領域ＯＬに対するＸ線細隙ビームＢの照射位置及び角度が変更されるように、撮像部昇降機構がＸ線発生器１０を歯列の並ぶ方向と交差する方向に互いに反対方向に昇降させると同時にビーム成形機構２２がＸ線細隙ビームＢの角度を変更することで、撮像機構３が撮影対象領域ＯＬの断層撮影を行う。【選択図】図１１ |
