BACKGROUND ART An X-ray imaging apparatus is widely used as a medical device for photographing an internal structure of a subject such as a patient or an animal.

A conventional X-ray photographing apparatus uses a photographic film which is irradiated from an X-ray generator and is sensitive to radiation passed through a subject, and images the internal structure of the subject.

However, since the X-ray emitted from the X-ray generator can not be visually recognized by the operator, it is difficult to discriminate the radiation position or radiation range of the X-ray to the patient to be measured.

In addition, the conventional X-ray generator has the risk that the emitted X-rays reach the operator even if the operator is away from the generator, thereby causing diseases caused by the X-ray to the operator.

The shielding member 401 is preferably made of a material such as lead to shield the X-rays emitted to the frame 200 side. The shielding member 401 is installed to surround the inner surface of the frame 200 and shields the X-rays irradiated to the frame 200 as described above, thereby limiting the irradiation range of the X-rays.

Since the X-ray target 100 capable of shielding the X-ray according to the present invention constructed as described above irradiates the guide light in the emitting direction of the X-ray, the operator can recognize the X-ray emitting direction or the emitting range The time and effort required for the photographing operation can be saved.

In the X-ray target 100 capable of shielding the X-rays according to the present invention, a shielding member 401 for shielding the X-rays is provided on the inner side surface of the through hole 211 of the frame 200 through which the X- The X-ray irradiated to the side of the inside of the X-ray tube 200 is blocked, thereby preventing the operator from having a disease caused by the X-ray.

5, a shield member 402 according to another embodiment of the present invention is shown.

Elements having the same functions as those in the previous drawings are denoted by the same reference numerals.

Referring to FIG. 3, the shielding member 402 is formed so that the protruding length from the inner surface of the frame 200 increases from the upper end adjacent to the X-ray generator toward the lower end. Since the thickness of the shielding member 402 corresponding to the exit side of the through hole 211 is thicker than the entrance side of the through hole 211 of the frame 200 through which the X-ray emitted from the X-ray generator is introduced, The thickness of the upper and lower portions of the shielding member 402 are different from each other, so that the material cost is reduced and the shielding member 402 can be manufactured at a relatively low cost.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.

Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
