The invention relates to the technical field of CT inspection, in particular to a CT inspection system. The CT inspection system comprises a rotary supporting frame, a scanning unit and a rotary driving device, a rotary driving unit of the rotary driving device comprises a supporting beam and two wheel driving mechanisms with driving wheels, the supporting beam is capable of swinging, the two wheel driving mechanisms are arranged on the supporting beam and located on two sides of the swinging center of the supporting beam, and the rotary supporting frame is driven to rotate to drive the scanning unit to rotate when the driving wheels rotate. Load is distributed to the other wheel driving mechanism by the supporting beam capable swinging when one of the wheel driving mechanisms located on two sides of the swinging center of the supporting beam is subjected to larger load so that pressure can be more equivalently borne by each wheel driving mechanism, and therefore a more stable rotary process of the rotary supporting frame can be achieved to effectively improve the rotary stability of a radioactive source device and a detecting device which are driven to rotate by the rotary supporting frame.
Description
technical field [0001] The invention relates to the technical field of CT detection, in particular to a CT inspection system. Background technique [0002] In addition to being used in the medical field, CT inspection systems are also widely used in technical fields such as item detection, and can not only detect small items such as bags and flight cases, but also detect larger items such as containers and vehicles. When working, the CT inspection system uses its radioactive source that generates high-energy X-rays and the detection device that can receive X-rays passing through the object to scan the object to be inspected, and reflects the change in the density distribution of the object to be inspected according to the change in X-ray intensity, and The ray intensity change is converted into image grayscale to obtain the perspective image of the object to be inspected. [0003] In the existing CT inspection system, the radioactive source device and the detection device a...
