Abstract: Disclosed are a method and a device for inspection of drugs concealed in liquid articles without opening the outer packages. The method comprises the steps of: emitting radiation beams to transmit through the liquid article; receiving the radiation beams transmitted through the liquid article to get multi-angle projection data; inversely operating the multi-angle projection data based on the uniformity of the liquid article to obtain an attribute value of the inspected liquid article; retrieving a reference attribute value in a pre-created database by using the identification information of the liquid article as an index, and calculating a difference between the calculated attribute value and the reference attribute value; and determining whether the difference is larger than a predefined threshold value; wherein it is concluded that there are drugs concealed in the liquid article when the difference is determined to be larger than the predefined threshold value.

Abstract translation: 公开了一种用于检查隐藏在液体制品中的药物的方法和装置，而不打开外包装。 该方法包括以下步骤：发射辐射束以透过液体物品; 接收透过液体物品的辐射束，得到多角度投影数据; 基于液体制品的均匀性反向操作多角度投影数据以获得被检液体的属性值; 通过使用液体物品的识别信息作为索引来检索预先创建的数据库中的参考属性值，以及计算所计算的属性值和参考属性值之间的差; 以及确定所述差异是否大于预定阈值; 其中，当确定差异大于预定阈值时，可以断定在液体制品中隐藏药物。
