As the first arm member 13 and the second arm member 23 are independently rotatable, the X-ray 1 of the first X-ray unit and the X-ray 1 of the second X-ray unit always cross vertically. It can be used in the state of crossing at various angles. Rotational movement around the rotational axis d of the first arm member 13 and rotational movement around the rotational axis d of the second arm member 23 are also expected by those skilled in the art. It is possible by means that can. For example, a rotational motion of the first arm member 13 may be possible by a linear motor in which the first arm member 13 is a mover and the first frame 14 is a stator.

The interval between the first transmitter 11 and the first receiver 12 may be adjusted by the sliding movement of the third plate 15. Similarly, a sixth plate 25 is provided below the second transmitter 21 so as to be slidable with respect to the second arm member 23 along the direction of the second axis b, and the sixth plate 25 is slid. The distance between the second transmitter 21 and the second receiver 22 may be adjusted by the exercise.

The X-ray projection device according to the present embodiment configured as described above may include a first X-ray unit emitting X-rays in a first axis direction and a second X-ray unit emitting X-rays in a second axis direction. It is possible to control the position accordingly. Therefore, in some cases, the position of the X-rays of the first X-ray unit and the X-rays of the second X-ray unit may be adjusted to meet at one point, so that any point of the object may be viewed in three dimensions, or the first X-ray may not be required in three dimensions. By adjusting the X-rays of the unit and the X-rays of the second X-ray unit so as to be staggered, a plurality of points of the object may be simultaneously viewed in a plan view, thereby reducing the perspective time. In addition, the X-ray projection device of the present embodiment can be used in accordance with a variety of situations, such as viewing a point of the object three-dimensionally or a plurality of points of the object in a planar view at the same time, the utilization of the device is high.

In addition, since the first X-ray unit projecting the object in the direction of the first axis and the second X-ray unit projecting the object in the direction of the second axis are detachably coupled, when combined, the single object can be projected in three dimensions. In the case of separation, different objects can be viewed simultaneously, thereby increasing the utilization of the device.

In addition, since the first X-ray unit and the second X-ray unit may be independently rotated around each center of curvature, the angle where the X-rays of the first X-ray unit and the X-rays of the second X-ray unit cross each other may be variously adjusted. Therefore, when projecting one point of the object three-dimensionally, two angles that can project the point most effectively can be arbitrarily selected, so that the inside of the object can be effectively projected.
