Abstract

The radiographic technique factors and the quality of each radiographic image for three common examinations (chest PA, pelvis AP and lumbar spine LAT) were compared with the European criteria and entrance surface dose (ESD) was measured for each radiograph in two Greek hospitals. The measurements were carried out using calibrated LiF thermoluminescence dosemeters. The patients were selected so that their weight was close to 70 +/- 10 kg and their height to 170 +/- 10 cm. Effective dose values were calculated using a PC-based Monte Carlo program. All four X ray rooms in the survey achieved mean doses well below the European reference doses. However the mean doses in the X ray rooms differed by a factor of about 3.

摘要

将希腊两家医院三种常见检查（胸部后前位、骨盆前后位和腰椎侧位）的放射成像技术参数及每张放射影像的质量与欧洲标准进行了比较，并测量了每张X光片的体表入射剂量（ESD）。测量使用经过校准的氟化锂热释光剂量仪进行。患者的选择标准为体重接近70±10千克，身高接近170±10厘米。使用基于计算机的蒙特卡罗程序计算有效剂量值。调查中的所有四个X光室的平均剂量均远低于欧洲参考剂量。然而，各X光室的平均剂量相差约3倍。
