Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a fixing table for a detection model body which is easy to adjust. Background Art

[0002] The dental phantom is a testing device specially used to test the imaging quality of dental CT equipment. The testing phantom is fixed on the CT equipment through a fixed bracket for testing, and can perform clear image scanning of oral panoramic X-rays, temporomandibular joint panoramic X-rays, head positioning anteroposterior and lateral X-rays, etc.

[0003] Unlike full-body CT scans, dental CT scans need to collect image data from multiple angles, so the model generally needs to have a certain displacement or deflection capability. Conventional dental models are fixed in design, and during testing, the dental model fixed on the fixed bracket needs to be manually disassembled for deflection or displacement. The disassembly and adjustment process is not only complicated and time-consuming, but also prone to errors, which can easily affect the scanning results. Therefore, improvements are needed to address the existing problems. Utility Model Content
