BGV6100 relocatable cargo & vehicle inspection system equips an electronic linear accelerator (Linac) and a new PCRT solid detector, which uses dual-energy X-ray and advanced material identification algorithms to achieve the perspective scanning and imaging cargo and vehicle, identify contraband goods. The system has two working modes: drive-through mode and mobile scanning mode. In mobile scanning mode, the system moves on the ground rail to scan the cargo vehicles. The system deployment takes into account the convenience of on-site use. An operation console is set at the entrance of the vehicle. The front-end guide personnel is responsible for starting the inspection process after the vehicle is ready, and can observe the entire inspection process throughout the process. Once an abnormality is found, the inspection process can be stopped immediately. After completing the interpretation of the vehicle imaging image, the rear-end vehicle image interpreter can communicate with the front-end guide through the console and can give the interpretation result through the corresponding warning signal.
