Description

本発明の一側面によれば、Ｘ線を発生する複数のＸ線ターゲットを支持するＸ線発生部と、前記複数のＸ線ターゲットのそれぞれに対応した複数の絞り孔の位置を調節可能なコリメータと、複数の制御モードに応じて前記複数の絞り孔を互いに連動して変更するように前記コリメータを制御する制御手段とをを有し、前記制御部は、第１の制御モードとして、前記複数の絞り孔を介して被写体にＸ線を互いに平行に照射するように前記コリメータを制御し、第２の制御モードとして、前記複数の絞り孔を介して被写体にＸ線を異なる角度で照射するように前記コリメータを制御することを特徴とするＸ線撮影装置が提供される。 According to one aspect of the present invention, an X-ray generator that supports a plurality of X-ray targets that generate X-rays, and a collimator capable of adjusting the positions of a plurality of apertures corresponding to the plurality of X-ray targets, respectively. And a control means for controlling the collimator so as to change the plurality of apertures in conjunction with each other in accordance with a plurality of control modes, and the control unit has the plurality of control modes as a first control mode. The collimator is controlled so as to irradiate the subject with X-rays in parallel with each other through the apertures, and as a second control mode, the subject is irradiated with X-rays at different angles through the plurality of apertures. An X-ray imaging apparatus is provided that controls the collimator .
