Abstract: This disclosure is directed to an X-ray security device having a main body, a conveyor, and a lead curtain. The main body has an opening. The conveyor passes through the opening and is disposed on a bottom of the opening. The lead curtain is hung on the main body and covers the opening, the lead curtain has a pair of outer modules and a central module, the pair of outer modules are arranged corresponding to two sides of a transport direction of the conveyor, and the central module is disposed between the outer modules. A lead equivalent thickness of each outer module is larger than a lead equivalent thickness of the central module, and a weight of the central module is less than a weight of each outer module.

Abstract: An X-ray imaging method includes the following steps: (a) performing a first object imaging and obtaining a first object intensity signal by detecting an X-ray passing through a first object; (b) performing baseline imaging process, obtaining a baseline intensity signal by detecting the X-ray when the first object is not in a FOV; and; (c) obtaining the first thickness of the first object by performing operations on the first object intensity signal, the baseline intensity signal, and the first attenuation coefficient of the first object.

Abstract: An imaging method for computed tomographic system (1) includes following steps of: controlling a computed tomographic system (1) to receive a description operation for configuring description data; selecting one of a plurality of imaging parameter sets corresponding to different template data, wherein each imaging parameter set is used to maximize a contrast-to-noise ratio of the three-dimensional imaging data (34) matching with the corresponding template data; and, controlling the computed tomographic system (1) to execute a three-dimensional imaging operation according to the selected imaging parameter set for obtaining the three-dimensional imaging data (34). The present disclosed example has the ability of effectively reducing a technical threshold of operating the computed tomographic system (1) via automatically selecting the suitable one of the complex imaging parameter sets according to the comprehensible description operation.
