[0002] As an X-ray imaging device, oral cone beam CT has played a huge role in the medical field since the beginning of the 21st century. The cone beam volume images obtained by this technology can help clinicians make better diagnoses of patients. In actual clinical applications, CBCT technology effectively solves the problems of image overlap and distortion in two-dimensional imaging. It solves most medical problems in dental implants, maxillofacial surgery, and periodontal diseases through three-dimensional imaging. This technology is of great significance to the future development and research in the medical field.

[0003] At present, most oral and maxillofacial CBCT products on the market are vertical structures. The patient stands, and the rotating imaging mechanism is located below the support arm.

The rotating imaging mechanism rotates around the vertical center axis to complete the imaging scan of the skull.

[0004] However, the above scheme has the following disadvantages: the requirements for the lifting column are high, and the height of the internal parts after lifting up and down is high, which easily causes the column to be unstable, resulting in a decrease in the accuracy of the photographic results. In addition, the existing device requires medical staff to adjust the position of the patient's head, which is inconvenient to use. Moreover, for patients lying flat, if they want to scan the oral and maxillofacial area before and during surgery to assist on-site surgery, they are powerless. Utility Model Content
