Abstract

A suite of technical performance standards is nearing completion that encompasses all the nation s security systems that screen using x-rays or gamma-rays. Specifically, these documentary standards address the aspects of imaging quality and radiation safety, and each specifies test artifacts, test methods, and in some cases required minimum performance levels. All modalities are treated: transmission and backscatter geometries as well as computed tomography (CT). The goal is to provide tools that for the first time provide governmental users and industrial partners uniform methods to compare technical aspects related to performance, and standard gauges that will stimulate and quantify future technological improvements.
