摘要/Abstract

摘要： 为了解湖南省X射线摄影设备(DR)6种主要检查部位不同的投照方位所致受检者的剂量水平,采用典型抽样法,在省内选取967例受检者作为调查样本,对常用的几种投照类型所致受检者的剂量进行调查。结果表明,湖南省内X射线摄影设备(DR),在腰椎前后位投照(AP)、腰椎侧位投照(LAT)、骨盆前后位投照(AP)、髋关节前后位投照(AP)、胸部后前位投照(PA)、胸部侧位投照(LAT)、胸椎前后位投照(AP)、胸椎侧位投照(LAT)、头颅后前位投照(PA)、头颅侧位投照(LAT)等部位投照时,所致受检者剂量的典型值分别为3.9、5.7、2.5、3.8、0.3、0.7、1.3、3.0、 0.7和0.7 mGy。无自动曝光控制(AEC)时,DR在胸部PA、胸部LAT摄影时所致受检者的剂量的平均值分别为0.77 mGy和1.44 mGy,有AEC时,DR在胸部PA、胸部LAT摄影时所致受检者的剂量的平均值分别为0.27 mGy和0.56 mGy。湖南省X射线摄影设备(DR)6种主要检查部位不同的投照方位所致受检者的剂量低于GB 18871—2002《电离辐射防护与辐射源安全基本标准》给出的典型成年受检者X射线摄影的剂量指导水平。在一定程度上, AEC能优化受检者在X射线摄影检查中受到的辐射剂量。

Abstract: To study the dose levels to patient from six main examination types in Hunan province. Using random sampling method, 967 patients were selected as the survey samples in research on the dose to patient receiving the common projection type. The typical dose values to patient were Lumbar(AP) 3.9 mGy,Lumbar spine(LAT) 5.7 mGy,Pelvis (AP) 2.5 mGy,hip joint (AP) 3.8 mGy,Chest (PA) 0.3 mGy,Chest (LAT) 0.7 mGy,thoracic (AP) 1.3 mGy,thoracic (LAT) 3.0 mGy,Skull (PA) 0.7 mGy,Skull (LAT) 0.7 mGy. The doses to Patient from the Chest (PA) and Chest (LAT) are 0.77 mGy and 1.44 mGy when the DR has the function AEC. The doses to Patient from the Chest (PA) and Chest (LAT) are 0.27 mGy and 0.56 mGy when the DR hasn’t the function AEC. The dose to patient receiving six types of X ray examinations by DR is lower than the dose Guidance Level in GB 18871—2002《Basic standards for protection against ionizing radiation and for the safety of radiation sources》in HUNAN province. The function of AEC has positive effect in dose controlling. To some extent,The function of AEC can optimize the dose receiving from X ray examinations by DR.
