AI Technical Summary
In existing dental X-ray imaging systems, patients tend to shake when examined while standing or sitting, resulting in poor examination quality. This is especially true for patients who are not tall enough, have difficulty moving, or have severe kyphosis, which increases the difficulty of operation and the amount of radiation.
An oral X-ray imaging system was designed, comprising a frame structure, an X-ray tube structure, and an examination bed structure. The system employs a supine position for examination and forms a U-shaped structure through a rotating arm, the X-ray tube body, and the detector structure. Combined with a slip ring power supply and power system, the X-ray tube and detector are rotated. The adjustable examination bed ensures stable positioning of the patient.
This technology enables oral X-ray examinations to be performed in a supine position, reducing patient movement, lowering radiation exposure, adapting to the examination needs of patients of different heights and with limited mobility, and improving examination quality and ease of operation.

TECHNICAL FIELD
[0001] The utility model relates to oral cavity technical field especially, it relates to a dental X -ray photography system. BACKGROUND
[0002] At present, in the medical process, many diseases need to carry out imageology examination. In terms of oral cavity imageology examination, panoramic film and CBCT etc. dental X -ray photography examination is used in a larger range.
[0003] The existing dental X -ray photography examination basically adopts standing or sitting position, and the patient stands or sits between the examination equipment ball tube and sensor, and the examination position is placed and positioned through adjusting the rack or guiding the patient to adjust the body position to complete the examination. However, no matter standing or sitting position, the patient is easy to produce the shaking under the influence of the body position, thereby affecting the examination quality. In addition, under the influence of the lifting height of the rack, the height of the patient is required to be higher, for the patient with shorter height, most of which are children, due to the limitation of the bottom limit of the rack, the patient needs to stand on a low stool, thereby increasing the probability of shaking and falling of the patient, and also increasing the difficulty of operation of the technician. For the patient with higher height, due to the highest limit of the height of the rack, the patient needs to separate the legs, half squat or sit on the stool to complete the examination, which also increases the probability of shaking and falling of the patient and the difficulty of operation of the technician. In addition, due to the aggravation of the problem of social aging, the patients with serious hunchback, unstable standing and inconvenient movement also increase relatively, and the patients with serious hunchback are limited by the distance between the ball tube and the detector, and the ball tube touches the shoulder during the examination, resulting in motion artifacts and substandard examination quality. For the patients with unstable standing, the family members need to support, and the position of the supporter may change due to the movement of the ball tube, thereby causing the generation of motion artifacts. For the patients with inconvenient movement, the examination is completed by sitting on a wheelchair, and since the push handle of most wheelchairs is higher than the shoulder of the patient, the operation difficulty is increased, and the ball tube may be touched, resulting in the failure of the examination. In order to obtain a more standard examination result, the patient may need to repeat several times, and the radiation dose of the patient is also relatively increased.
