Description

Dental portable X-ray imaging device {Dental portable X-ray imaging device}

The present invention relates to a portable dental X-ray imaging apparatus, and more particularly, to a dental portable X-ray imaging apparatus capable of performing X-ray imaging of an oral cavity of a subject.

The dental portable X-ray imaging device was first manufactured for the military field use in the United States in 1993, and in Japan, it is used for emergency treatment for at-home patients such as the disabled. Because of the convenience of being able to sit on a chair and take a picture, various products are being widely used in dental clinics.

Since the portable X-ray imaging device for dental use is taken by the photographer holding it in his/her hand, exposure of the photographer's hand due to radiation leaking during the imaging process and the exposure of the photographer's body due to scattered radiation from the subject may be a problem, so it is safe to use. Guidelines for this are required.

The above-described portable X-ray imaging apparatus for dentistry has the advantage of being easy to use, and it is necessary to accurately target the radiation position of X-rays due to the small imaging range. There is a problem that cannot be done.
