Dental X-ray imaging system with sterilization function {DENTAL X-RAY IMAGING SYSTEM WITH STERILIZATION FUNCTION}

The present invention relates to a dental X-ray imaging system having a sterilization function, and to a dental X-ray imaging system having a sterilization function while solving a vibration problem that occurs during X-ray imaging and obtaining a clearer image frame.

Among them, the panoramic image can observe the entire area of the teeth and alveolar bone in a planar view, but there are cases where the teeth are slightly tilted forward and backward or it is not possible to determine the malocclusion of a part of the dentition. Although it can compensate for the shortcomings, there is a disadvantage that the entire area of the teeth and alveolar bone cannot be grasped at once.

Therefore, the panoramic image and the cephalo image are often used at the same time due to the complementary nature as described above. The use of dental X-ray imaging devices capable of taking images is also increasing.

A conventional X-ray irradiation device irradiates a cone-shaped X-ray beam from a small X-ray irradiation unit such as a point light source. Since the cephalo image capture requires irradiation of an X-ray beam in a wider range than a panoramic image, the X-ray irradiation unit Cephalo detectors are installed and used by separating them to a distance where the irradiated cone-shaped X-ray beam is spread as much as necessary.

However, since the above-described dental X-ray image photographing apparatus has the X-ray source device and the X-ray detection device spaced apart from the support pillar, when vibration is applied to the building in which the dental X-ray imaging apparatus is installed, the X-ray source apparatus and the X-ray detection apparatus There is a problem that it shakes.

Furthermore, the above-described dental X-ray imaging apparatus does not suggest a sterilization function capable of automatically sterilizing the jaw support in contact with the body of the target object.
