Abstract

The various forms of tomography, expressed as transmission and emission modes using gamma rays and neutrons, are generally discussed in terms of providing information nondestructively about the distribution of elemental composition in a plane through an object. The combination of the principles of tomography with neutron activation analysis is the basis for neutron-induced gamma-ray emission tomography. The concept of detection limit in induced gamma-ray emission tomography, as proposed, incorporates a further factor that is a measure of the quality of the image produced. A specific example is given for the elemental analysis and imaging of a bone specimen.

摘要

断层扫描的各种形式,以使用伽马射线和中子的透射和发射模式表示,通常是在无损提供有关穿过物体的平面中元素组成分布信息的层面上进行讨论。断层扫描原理与中子活化分析的结合是中子诱发伽马射线发射断层扫描的基础。所提出的诱发伽马射线发射断层扫描中的检测限概念纳入了另一个因素,该因素是对所产生图像质量的一种度量。给出了一个用于骨标本元素分析和成像的具体示例。
