Description

Technical Field

[0001] The utility model relates to the technical field of CBCT, in particular to a base support frame and CBCT equipment. Background Art

[0002] CBCT is the abbreviation of Cone beam CT. As the name suggests, it is a cone beam projection computer reconstruction tomography device. Its principle is that the X-ray generator performs circular digital projection (DR) around the projection object with a lower amount of radiation. Then the data obtained from the intersection of multiple digital projections around the projection object is reorganized in the computer to obtain a three-dimensional image. The projection principle of CBCT to obtain data is completely different from that of traditional sector scanning CT, but the algorithm principle of the later computer reconstruction is similar. Oral CBCT has the advantages of clear images, high resolution, short reconstruction time, and can eliminate waiting troubles. It also has the most reasonable imaging range, and a three-dimensional stereoscopic image of the entire oral cavity and double dentition can be obtained in one scan.

[0003] Currently in the CBCT field, CBCT devices all adopt a suspended structure. The device itself does not have the function of carrying patients, and patients can only be photographed in a standing manner. For some weak patients, this photographing and examination method is extremely inconvenient. Therefore, a base support frame and a CBCT device are proposed. Utility Model Content
