摘要
目前数字减影血管造影系统在疾病治疗中发挥越来越重要的作用,且已在各大医院广泛应用,同时对医院密集人口的辐射影响也引起人们关注。本文介绍了数字减影血管造影系统工作原理及其治疗室的辐射防护,通过对数字减影血管造影系统治疗室周围辐射环境的监测结果和相关工作人员剂量估算,预测可能对相关工作人员及对周围环境的辐射影响;通过对系统防护安全、事故应急预防和管理要求的分析,评价数字减影血管造影系统运行安全的可靠性。
At present,digital subtraction angiography system plays an increasingly important role in the treatment of diseases,and has been widely used in major hospitals,while the impact of radiation on the hospital population has also attracted people’s attention.This paper describes the principle of digital subtraction angiography system and its treatment room radiation protection,through the digital subtraction angiography system around the treatment room radiation monitoring results and related staff dose estimates,the forecast may be related to the staff and the And the reliability of the digital subtraction angiography system is evaluated by analyzing the requirements of system protection and accident emergency prevention and management.
