CAH-I放疗束流分析仪的研制

Development of CAH - I radiotherapy beam flux analyzer

本文介绍一种测量剂量分布的仪器，通过单一半导体探头在一维传动机构运动，达到一线扫描测量的目的。仪器还具有定时期分输出剂量的测量功能。仪器采用单片机进行数据采集、数据处理、数据显示及数据打印输出，是放射治疗和质量保证（QA）的一种非常安全。方便的测量仪器。

An analyzer to measure dose distributions is introduced in the paper. One - dimensionalscanning measurement is accomplished through one - dimensional transimission machanism with siglediode detector. There is measurement function of rate/integrate dose outputs in the analyzer. A micro-contraller is used for data sampling, processing, displaying, printing. The analyzer is safe and successfulin radiotherapy and quality assurance (QA).
