    • The present invention discloses a gantry configuration for a combined mobile radiation inspection system comprising a first arm frame, a second arm frame and a third arm frame. The first, second and third arm frames define a scanning channel to allow an inspected object to pass therethrough. The gantry configuration for the combined mobile radiation inspection system further comprises a position sensing device configured to detect a position error between the first arm frame and the second arm frame; and a controller configured to control a moving speed of at least one of the first arm frame and the second arm frame based on the detected position error, so that the position error between the first arm frame and the second arm frame is equal to zero. Compared with the prior art, the present invention is advantageous at least in that an automatic deviation correction device is provided on the gantry arm frame, and thus the position error between both side arm frames can be automatically controlled to zero, so that the gantry arm frame can be effectively prevented from being subjected to a force and deforming, and the radiation detector can receive the full ray, thereby improving the imaging quality.
    • 本发明公开了一种用于组合的移动辐射检查系统的机架结构,其包括第一臂架,第二臂架和第三臂架。 第一,第二和第三臂架限定扫描通道以允许被检查物体通过。 组合移动辐射检查系统的台架结构还包括一个位置检测装置,其配置成检测第一臂架和第二臂架之间的位置误差; 以及控制器,其被配置为基于所检测的位置误差来控制所述第一臂框架和所述第二臂架中的至少一个的移动速度,使得所述第一臂框架和所述第二臂架之间的位置误差等于零。 与现有技术相比,本发明至少是在台架臂架上设置自动偏差校正装置是有利的,因此两侧臂架之间的位置误差可被自动控制为零,使得机架臂 可以有效地防止框架受到力和变形,并且放射线检测器可以接收全光线,从而提高成像质量。
