Abstract

This study aimed to assess patient entrance surface air kerma (ESAK) during chest and abdominal X-ray procedures in screen film radiography (SFR) and computed radiography (CR) to establish dose reference levels. Patients' doses were measured in five hospitals for a total of 196 patients. ESAK was calculated from exposure parameters using DosCal software. The X-ray tube output (mGy mAs(-1)), accuracy of exposure factors, linearity and reproducibility were measured using an Unfors Xi dosimeter. The overall mean and range of ESAK during chest X-ray were 0.6 ± 0.3 (0.1-1.3) mGy, while for abdominal X-rays they were 4.0 ± 3.2 (1.3-9.2) mGy. Hospital with a CR system was found to use relatively higher doses. Dose values for abdominal X-ray procedures were comparable with previous studies. The dose for chest X-ray procedure was higher by a factor of 2-3 compared with the current international reference levels.

摘要

本研究旨在评估在屏片摄影（SFR）和计算机X线摄影（CR）中进行胸部和腹部X线检查时患者的入射表面空气比释动能（ESAK），以建立剂量参考水平。在五家医院对总共196名患者的剂量进行了测量。使用DosCal软件根据曝光参数计算ESAK。使用Unfors Xi剂量仪测量X射线管输出（mGy mAs⁻¹）、曝光因子的准确性、线性和再现性。胸部X线检查期间ESAK的总体平均值和范围为0.6±0.3（0.1 - 1.3）mGy，而腹部X线检查时为4.0±3.2（1.3 - 9.2）mGy。发现配备CR系统的医院使用的剂量相对较高。腹部X线检查程序的剂量值与先前的研究相当。胸部X线检查程序的剂量比当前国际参考水平高2至3倍。
