This document establishes standards for the technical performance of cabinet x-ray imaging systems usedfor screening at security checkpoints and other inspection venues. Included are all x-ray systems designedprimarily for the inspection of baggage at airline, railroad, and bus terminals, and in similar facilities. An xraytube used within a shielded part of a building, or x-ray equipment that may temporarily or occasionallyincorporate portable shielding, is not considered to be a cabinet x-ray system.
Purpose
contraband materials, as well as to verify manifests (to determine that the contents of a package are whatthey are purported to be). For these applications, this standard is intended to provide procurers and/orprospective users of checkpoint x-ray systems with: test methods that facilitate performance comparisonsamong systems, and the minimum acceptable imaging-performance requirements. These values areachievable in the current state of the art of production checkpoint x-ray systems. Additionally, a variety offactors essential for the safe operation of checkpoint x-ray systems are assembled and standardized in thisdocument.While it appears logical that better imaging performance will result in better screening performance, theuser is cautioned that the correlation between specific imaging-performance metrics and detectionperformance has not been established on a strict scientific basis. In addition, there may be trade-offs amongimaging-performance parameters. For example, higher penetration may result in decreased contrastsensitivity. Consequently, users are encouraged to evaluate candidate checkpoint x-ray systems againsttheir specific requirements whenever possible, and especially in cases in which the application is atypical.The tests specified in this standard may be used for type testing. Type tests are intended to demonstrate thatproduction systems made according to a specific design meet defined performance criteria.
Abstract
