医用诊断X射线剂量探测技术概述

Introduction of diagnose X-ray dose testing technology

本文介绍了诊断X射线剂量检测方法,重点论述了其中的关键--基于电离室和半导体技术的辐射剂量探测原理,传感器结构、用途以及各自的特点,对测量不同对象和参量探测器的选择提出了参考意见。本文还提出了近年发展起来的新技术———复合探测器概念以及在诊断X射线质量保证技术上的优势,提出了X射线探测器发展趋势。

This paper introduces the testing method of diagnose X-ray dose , and discusses the chamber and semiconductor used in X-ray detector theory , structure and it's characteristics.How to select detector for each measure have been suggested.A new detector mix chamber and semiconductor can be used test kV、mA、exposure time、dose and doserate of X-ray unit discribes subsequently.
