摘要

本文根据γ光子与物质相互作用的原理，设计和研制了主要用于测量人活体桡骨矿物质含最的

125

I单光子骨矿物质分析仪。文中介绍了分析仪的原理、基本结构、性能分析、数据处理方法、曲线刻度方法、误差分析和临床初步应用等。该仪器测量结果的线性和重复性均良好，测量精度好于±5%，性能可靠，操作方便，测量迅速，能定量分析，是一种无创伤的检查仪，可以推广应用于医学研究和临床。

Abstract

Based on the interaction between γ-photon and the matter

125

I single-photon analyser for measuring mineral content of radius in vivo was designed. The principle

basic structure and characteristics for the analyser were described. Data processing

curve calibration

error analysis and preliminary clinic application were also presented. This instrument has good linearity and reproducibility

and a precision of ±5%. It is reliable

easy to operate

quick to measure and able to be quantitative. Being non-traumatic

the instrument can be extented to medical science as well as clinic applications.
