心血管介入诊疗中术者的辐射防护与安全的探讨

Radiation Protection and Safety of Cardiovascular Interventional Diagnosis and Treatment of Surgeon

目的:探讨心血管介入诊疗中影响术者辐射防护与安全的相关因素并对术者的放射防护提出的相关建议。方法:使用多用剂量、TLD剂量片和头胸腹拟人模体分别测定术中术者所站立的重要区域、遮光器大小改变、检查床到影像增强器的距离、影像增强器照射野变化时术者所接受的辐射剂量值,并进行对比分析。结果:成功测定术者相关影响因素变化时的辐射剂量值,并绘制介入诊疗中术者站立区域剂量分布示意图,测定并给出遮光器大小、检查床到影像增强器的距离、影像增强器照射野变化时术者的辐射剂量值。结论:术者站立的区域、遮光器、距离、影像增强器照射野等参数的选择都会影响到术者辐射防护与安全,同时应注意联合选用多种放射防护措施进行保护。

Objective： To Explore Cardiovascular Interventions affect the surgeon in the diagnosis and treatment of radiation protection and safety and put forward relevant proposals made by the radiological protection of operators.Methods： The use of multi-dose,the TLD dose tablets and head thoracoabdominal intends people die body respectively determination intraoperative surgery by the standing of important regional changes in the size of the chopper,check the bed to the image intensifier of the distance,the image intensifier irradiated wild changes in patients whothe dose of radiation received value,and for comparative analysis.Results： Successfully measured surgeon related factors change the radiation dose values,and plotted involved in the diagnosis and treatment of patients who stand region dose distribution diagram measured and given the size of the chopper,the examination bed to the distance of the image intensifier,the image intensifier radiation field changesintraoperative radiation dose values.Conclusions： The surgeon standing area,shading,distance,image intensifier,radiation field size,etc.affect the radiation Protection and Safety,the surgeon should be used in a variety of radiological protection measures for its protection.
