    摘要： A radiation protection arrangement, including: a housing, the housing including a first port and a second port; and a tray, the tray having an accommodation space. The tray is allowed to pass through a channel within the housing. The tray has a first end wall, a second end wall, and a bottom portion connected between the first end wall and the second end wall. A shape of the first end wall and/or a shape of the second end wall are/is configured to fit with an inner wall of the housing, so as to block a radiation from leaving the channel from the accommodation space through the second port or the first port. Further provided is a security inspection device, including the radiation protection arrangement.

    摘要： The present disclosure discloses a detector device comprising a plurality of detector assemblies. Each detector assembly comprises at least one detection crystal units having a first energy response and those having a second energy response, which are both arranged along a first direction at intervals, each detection crystal unit having a first/second energy response including at least one detection crystals having a first/second energy response arranged along a second direction. The at least one detection crystal units having a first energy response and the at least one detection crystal units having a second energy response are, at least partially, alternatively arranged along the first direction when viewed from an incidence direction of the X-ray. The present disclosure also discloses a dual energy CT system having the detector device and a CT detection method using this system.

    摘要： Disclosed are object detection method, display methods and apparatuses. The method includes obtaining slice data of inspected luggage in the CT system; generating 3D volume data of objects in the luggage from the slice data; for each object, determining a semantic description including at least a quantifier description of the object based on the 3D volume data; and upon reception of a user selection of an object, presenting the semantic description of the selected object while displaying a 3D image of the object. The above solutions can create a 3D model for objects in the inspected luggage in a relatively accurate manner, and thus provide better basis for subsequent shape feature extraction and security inspection, and reduce omission factor.
