Abstract: An inspection system included a ray source to emit a ray, a detector to receive the ray, a detection region for placing an object under inspection, and a moving device to move the ray source and the detector around the detection region. Conventional scanning blind zones such as both sides of a human body, both sides of arms and both sides of legs can be completely eliminated. In addition, it is not necessary for a human body under inspection to carry out an action such as turning around to change his or her posture. Therefore, ineffective time can be minimized in the entire detection and a passing rate of persons under inspection can be improved. Furthermore, an inspected person's mental feeling of being controlled due to change of posture can be greatly improved, and his or her mental discomfort and conflicted moods can be reduced.
Abstract translation: 检查系统包括用于发射射线的射线源,用于接收射线的检测器,用于放置被检查物体的检测区域,以及使检测区域周围的射线源和检测器移动的移动装置。 可以完全消除诸如人体两侧,臂的两侧和腿的两侧的常规扫描盲区。 此外,被检查的人体不需要进行转动等动作来改变姿势。 因此,在整个检测中无效时间可以最小化,可以提高检查人员的合格率。 此外,被检查者由于姿势变化而受到控制的心理感觉可以大大提高,并且可以减轻他或她的精神不适和冲动的情绪。
