Abstract

The invention discloses a container CT inspection system, which includes a scanning device, the scanning device includes a radioactive source device and a detector array, and the scanning device also includes a first track and a second track arranged in two layers inside and outside, wherein the The radiation source device is arranged on the first track, and the detector array is arranged on the second track. The invention realizes that the radioactive source device and the detector array are respectively supported by different rails, and improves the current situation that the circular rotating frame needs to carry a large load. For each rail in the first rail and the second rail, the strength requirements Compared with the ring-shaped rotating frame, it is greatly reduced, so compared with the container CT inspection system in the prior art, the processing difficulty is effectively reduced.

Description

technical field [0001] The invention relates to the field of container inspection equipment, in particular to a container CT inspection system. Background technique [0002] In the prior art, the transmissive container inspection system has been able to detect suspicious objects in the container very well, but the false detection rate is high, which makes the customs conduct unnecessary unpacking inspections many times. The container CT inspection system can provide three-dimensional images and can identify substances, which can greatly reduce the false detection rate. [0003] The invention patent application with publication number CN1779448A discloses a container inspection system with CT tomography function, which can be used as a single-view transmission imaging system. When a suspicious object is found, a CT scan is performed in the vicinity of the suspicious object. figure 1 A schematic structural diagram of the container inspection system is shown. [0004] Such a...
