[0002] CT, or computer tomography, uses precisely collimated X-ray beams, gamma rays, ultrasound, etc., together with highly sensitive detectors to scan sections of a certain part of the human body one by one. It has the characteristics of fast scanning time and clear images, and can be used to examine a variety of diseases. The main components of CT equipment include the emission source, detector, rack, bed, and data acquisition and processing system. When working, the emission source emits X-rays, which will penetrate the human body or the object being measured. After the detector receives the X-rays, it converts them into electrical signals. The data acquisition and processing system transmits the electrical signals to the image reconstruction system for image reconstruction, thereby obtaining a CT image.

[0030] First, the rotating shaft 110 is passed through the flat plate 40 and the L-shaped bracket 30, and then the retaining ring 120 is clamped on the outer wall of the end of the rotating shaft 110 and abutted against the inner wall of the L-shaped bracket 30, so that the detector 10 can be clamped on the flat plate 40, and then the detector 10 and the flat plate 40 are rotated as needed, so that the detector 10 and the flat plate 40 can be rotated along the axial direction of the rotating shaft 110 relative to the vertical plane of the L-shaped bracket 30, and then the horizontal angle of the detector 10 can be adjusted to facilitate the reception of X-rays from different directions.

[0031] It should be noted that, in order to enable the retaining ring 120 to be stably stuck on the rotating shaft 110, the retaining ring 120 is made of rubber material, and a groove matching the retaining ring 120 is opened on the outer wall of the rotating shaft 110 away from the detector 10; after the rotating shaft 110 passes through the flat plate 40 and the L-shaped bracket 30, the retaining ring 120 can be pried open first, and the retaining ring 120 can be inserted into the groove on the outer wall of the rotating shaft 110, and then the retaining ring 120 can be loosened.

[0035] Place the back of the detector 10 against the surface of the "I"-shaped flat plate 40, and then pass the fastening bolt 50 through the mounting portion 420 and screw it into the screw hole on the back of the detector 10. The detector 10 can be installed on the flat plate 40 first, so that it is convenient to rotate the detector 10 and the flat plate 40 at the same time to adjust the angle of the detector 10.
