Abstract

The useability of external-beam proton-induced X-ray (PIXE) and gamma-ray (PIGE) emission, backscattering spectrometry (BS), and the particle-particle method in biomedical work is demonstrated. Detection limit values obtainable by the methods for typical biomedical samples under practical conditions are given and compared. Advantages, drawbacks, and restrictions of the methods are discussed. Examples of the applications of the methods in biomedical work are given.

摘要

本文介绍了外照射质子诱发 X 射线（PIXE）和伽马射线（PIGE）发射、背散射谱（BS）以及粒子-粒子法在生物医学工作中的应用。给出了在实际条件下典型生物医学样品用这些方法可获得的检测限，并对其进行了比较。讨论了这些方法的优缺点和限制。本文还给出了这些方法在生物医学工作中的应用实例。
