IEC 62945:2018提供了评估计算机断层扫描（CT）安检系统图像质量的测试方法。自动化分析的数据质量是首要关注的问题。安全检查系统通常用于扫描包裹（包括行李）是否存在非法物品，如爆炸物、毒品或其他违禁品。目前使用的许多筛查系统，特别是在运输安全应用中，是基于CT成像技术的。

IEC 62945:2018 provides test methods for the evaluation of image quality of computed tomography (CT) security-screening systems. The quality of data for automated analysis is the primary concern. Security screening systems are generally used to scan parcels, including luggage, for the presence of illicit items such as explosives, drugs, or other contraband. Many of the screening systems currently used, particularly in transportation security applications, are based on CT imaging technology.
