Abstract
Description
The present invention relates to a radiation scattering prevention apparatus for a radiation inspection apparatus, and more particularly to a radiation scattering prevention apparatus for a radiation inspection apparatus which is detachably attachable to a radiation generating unit from which radiation is emitted and has a structure in which a length adjusting unit can be dismantled, But it is designed so that the length of the radiation can be adjusted toward the subject to be irradiated, thereby preventing the scattering radiation from deteriorating the quality of the image and reducing the occurrence of radiation exposure due to scattering of radiation outside the imaging site. Scattering prevention mechanism.
An X-ray inspection apparatus irradiates a subject or a subject (hereinafter referred to as "subject") with radiation, detects an X-ray passing through the subject and obtains an image. Based on the image, the X- It is used for various purposes such as industrial use, medical use, learning use, inspection test, and the like.
This X-ray inspection apparatus accelerates the hot electrons heated from the cathode and collides with a target to generate an X-ray. The generated X-ray passes through the irradiation field adjusted by the radiation workers, object.
When interacting with the subject, the X-ray is attenuated due to factors such as thickness and atomic number of the subject, resulting in dose differences. In this case, when the X-ray having the difference of the attenuation is positioned behind the subject and reaches the film formed by the image, that is, the imaging plate (IP) or the CCD detector (Charge Coupled Device Detector) And this makes the image.
In this process, an out-of-focus X-ray (hereinafter referred to as a scattering line) is generated. This scattering line is a phenomenon in which the secondary electrons generated from the target of high-speed electrons interact with each other at the bottom surface other than the bottom surface. Most scatter lines are generated by the interaction of the X-rays originating from the focus with the air or the subject.
However, since the generated scattering line causes degradation of image quality and exposure of the subject and radiation workers, there is a need to reduce them to improve the image quality and reduce the exposure.
In order to shield the X-ray exposure, a shielding material is used. The material used as a shielding material uses a heavy atomic mass as compared with atoms of other materials. The reason for this is that when the X-ray passes through the shielding material having a heavy mass of atoms, the shielding effect is improved because more collisions occur than when passing through the shielding material composed of light atoms.
However, in the case of a radiological examination apparatus used for general medical use, it is necessary to minimize the body part exposed to radiation because direct radiation is applied to the body part of the subject to acquire necessary images. However, in the medical radiological examination apparatus A uniform distance is maintained between the radiation generating part in which the radiation is generated and the subject, so that even when the radiation is directed toward a specific part of the body, the radiation is scattered to the area other than the target part, And it is known that it adversely affects health.
Of course, in the case of a radiography apparatus equipped with a radiological examination apparatus, a shielding material for preventing radiation scattering is installed behind a subject to be irradiated, thereby preventing scattering of radiation passing through the subject, thereby reducing radiation exposure , Which is merely a device for preventing back scattering of the subject.
Therefore, as the development of medical diagnosis technology and the incidence of cancer-related diseases increase, the treatment and examination using radiation are becoming more and more widespread, and unnecessary radiation is irradiated to the subject during radiation imaging, There is a need to find a solution to this problem.
Disclosure of the Invention The present invention has been conceived to overcome the disadvantages of the conventional radiographic examination apparatuses, and it is an object of the present invention to provide a radiographic apparatus and a radiographic image capturing apparatus capable of preventing radiation scattering between an examination apparatus irradiated with radiation and a subject, And an object of the present invention is to provide a radiation scattering prevention apparatus for an inspection apparatus.
In addition, the present invention is not only capable of adjusting the length according to the distance from the subject, which is a radiographic object, but also facilitating detachment and attachment to a radiological examination apparatus, thereby effectively preventing radiation exposure at unnecessary sites, The present invention also provides a radiation scattering prevention apparatus for use in a radiation inspection apparatus,
In order to achieve the above object, a radiation scattering prevention mechanism for a radiation inspection apparatus according to the present invention is characterized by comprising: a fixing member having a penetrating portion formed at a central portion thereof and detachably fixed to the outer surface of the radiation generating portion of the radiation testing device; The fixing member has a hollow shape having one end connected to a rim portion of the fixing member and protruding by a predetermined length in a direction perpendicular to the fixing member, and a radiation shielding member having a predetermined thickness is formed on the inner circumferential surface of the fixing member. Radiation scattering cover; .
Particularly, the fixing member is configured such that its outer frame portion is fitted on the outer surface of the radiation generating portion of the radiation examination apparatus in a sliding manner to facilitate detachment and detachment, and a plurality of hollow tubes having a predetermined length, Or can be fitted to the outside so as to be adjustable in a telescopic manner.
The scattering prevention cover has a first hollow tube having an outer diameter of the largest diameter connected to the fixing member, a second hollow tube having a diameter smaller than that of the first hollow tube so as to be in close contact with the inner side surface of the first hollow tube, And a third hollow tube having a diameter smaller than that of the second hollow tube is fitted and coupled to an inner surface of the second hollow tube, wherein the inner peripheral surface of the first hollow tube, the outer peripheral surface of the second hollow tube, And the outer circumferential surface of the third hollow tube is provided with a take-out length adjusting unit for preventing the second hollow tube and the third hollow tube from being drawn out by their own weight.

The radiation scattering prevention device for a radiation examination apparatus according to the present invention can prevent unnecessary film exposures from being exposed outside of a photographed region, thereby eliminating unwanted images, thereby improving sharpness of the image. In addition, By preventing scattering lines, unnecessary exposure to the image can be reduced and the quality of the image can be improved
In addition, by reducing the area of a subject in which scattered rays are generated by interaction between radiation, air, and the subject, it is possible to reduce the damage caused by the scattered rays and the operator of the inspection apparatus.
Further, according to the present invention, the length can be adjusted according to the distance from the subject, so that the quality of the photographed image can be improved by preventing the radiation of the photographed region from being concentrated and scattered.
