The present invention has the effect of displaying the position of the X-ray imaging with the laser amer 200 so that the X-ray imaging of the part desired by the operator can be accurately made by one X-ray imaging.

According to the present invention, the X-ray imaging of the part desired by the operator can be accurately performed by a single X-ray, which greatly reduces the radiation exposure delivered to the patient and the operator, and prevents a disease that may be caused by the patient and the operator being exposed to the radiation. It can be effective.

The present invention can accurately set the initial reference position when mounted on the x-ray imaging apparatus, and when the point position of the laser amer 200 does not match the correct position due to assembly tolerances when assembling the tube 11 of the x-ray generating unit, By adjusting the position of the amer 200, there is an effect of accurately displaying the X-ray photographing position of the patient through the laser amer 200.

The present invention is not limited to the above-described embodiments, but can be modified and practiced in various ways without departing from the gist of the present invention, which is understood to be included in the configuration of the present invention.
