摘　　要：用ＳＭＮ－Ｉ型仿真男性人体模型，按照医院常规要求模拟患者接受ＣＴ扫描检查，测定ＣＴ扫描时眼晶体、甲状腺、睾丸的屏蔽前、后Ｘ线辐射剂量。结果：距离ＣＴ扫描部位较近的上述重要器官屏蔽前后Ｘ线辐射剂量差异显著。表明ＣＴ检查时有必要对距离ＣＴ扫描部位较近的重要器官采取防护措施。In this work,the SMN-I anthropomorphic phantom was used to simulate patients and to estimat the radiation exposure of lens,thyroid gland and testis during CT examination according to hospital routine managements,The results show that the X-ray radiation doses received by the organs mentioned above are different in good and no pretection shelter,Therefore,during CT examination it's of great significence to take a good protective shelter for organs which are near the CT scanning areas.

关 键 词：CT 仿真人体模型 辐射剂量 屏蔽防护 眼晶体
