Oral cavity CBCT equipment

Abstract

The invention discloses an oral cavity CBCT equipment, a cantilever is arranged at the top of a supporting frame, and a supporting table is connected to the supporting frame and used for supporting the head of a patient. An X-ray assembly is arranged at one end of a C-shaped arm and the X-ray assembly is provided with an X-ray source. A CT detection assembly is arranged at the other end of the C-shaped arm, and the CT detection assembly and the X-ray assembly are located on the two opposite sides of the head of the patient. A movement driving assembly is used for driving the CT detection assembly to move between a first position and a second position. A head side position device comprises a secondary beam limiting device and a head side position detector, and the head side position detector is connected to the cantilever and used for receiving X-rays which come from the X-ray source and pass through the secondary beam limiting device. Wherein the CT detection assembly is used for receiving X-rays when being located at the first position, and the CT detection assembly is used for avoiding the X-rays from the X-ray source to the secondary beam limiting device when being located at the second position. According to the oral cavity CBCT equipment, the structure is simple, the production cost is low, the imaging view can be adjusted in a stepless mode, and the requirements of different doctors are met.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to oral cavity CBCT equipment. Background technique [0002] In related technologies, oral CBCT equipment (oral cone beam projection computerized tomography imaging equipment) often has the function of cephalometric imaging in order to meet the orthodontic needs of maxillofacial and whole head, and the principle of this function is a linear scan method. Due to the limitation of the overall layout of the equipment, it is necessary to keep the X-ray away from the CT detection component and its supporting parts when taking a cephalometric view. In order to solve this contradiction, the function is generally realized in the following ways. The first way is that the X-ray source rotates and the cephalometric detector moves; the second way is that the CT detection component is detachable and the head is shot Remove it when sideways. [0003] The disadvantage of the first met...

AI Technical Summary

Problems solved by technology

Generally, the larger the area of ​​the detector, the larger the FOV, but the cost of the detector increases exponentially, and the cost of the equipment will also increase accordingly; the more the relative position (horizontal direction) of the detector and the X-ray source deviates , the larger D is, but this method cannot be adjusted steplessly and cannot meet the different needs of different doctors
