    • An X-ray generation unit and an X-ray detection unit are held by an arm. Image data is generated based on X-ray projection data which is generated by the X-ray detection unit. A first support member supports the arm and rotates the arm in a first rotation direction. A second support member supports the first support member. The second support member rotates the first support member around a rotation center in a second rotation direction perpendicular to the first rotation direction. A movement unit can move the second support member in an up and down direction.
    • X射线产生单元和X射线检测单元由臂保持。 基于由X射线检测单元生成的X射线投影数据生成图像数据。 第一支撑构件支撑臂并使臂沿第一旋转方向旋转。 第二支撑构件支撑第一支撑构件。 第二支撑构件沿与第一旋转方向正交的第二旋转方向围绕旋转中心旋转第一支撑构件。 移动单元可以沿上下方向移动第二支撑构件。
