基于双源扫描的电离辐射检测
摘要：
一种基于双源扫描的辐射检测设备，该设备包括至少两个辐射源(11a、11b)，其用于发射电离辐射；排列成阵列的多个方向敏感的线检测器(16a)；和用于使所述线检测器(16a)在扫描方向(x)上对待检验物体进行扫描的装置(17－19，21－22)，其中所述阵列中的线检测器指向所述辐射源；并且所述用于扫描的装置被设置为在扫描期间使所述线检测器与所述辐射源保持对准，以使各个线检测器能够记录所述对象的多个线图像。根据本发明，所述阵列中的线检测器(16a)是方向敏感的并且交替地指向所述辐射源中的不同辐射源；并且所述辐射源被排列在所述扫描方向(x)所在的平面中。
摘要（英）：

A dual-source scanning-based radiation detecting apparatus comprises at least two radiation sources (11a-b) provided for emitting ionizing radiation; direction sensitive line detectors (16a) arranged in an array; and a device (17-19, 21-22) for scanning the line detectors (16a) in a scanning direction (x) across an object to be examined, wherein the line detectors in the array are pointing towards the radiation sources; and the device for scanning is arranged for keeping the line detectors aligned with the radiation sources during scanning to enable each of the line detectors to record multiple line images of the object. In accordance with the invention the line detectors (16a) in the array are direction sensitive and are alternately pointing towards different ones of the radiation sources; and the radiation sources are arranged in a plane, in which the scanning direction (x) lies.
