Image quality and patient doses received during chest bedside examinations performed with conventional (film-screen combination) and photostimulable phosphorus plate systems were compared in a study carried out in 1993 in a French pediatric radiology department. Seventy one children (36 males and 35 females) aged between 9 days and 18 years (average: 43 months) were included in the study. Technical performances of all radiological equipment used were permanently checked through a quality control program. One conventional and 3 "photostimulable" films were performed for each patient included (mAs product selected for "photostimulable" system was progressively reduced down to 60% of that of conventional technique). TLD Lithium Fluoride chips were used to measure entrance surface dose during the examination. Image quality of 284 films (213 "photostimulable" + 71 conventional) was assessed by three independent radiologists. Advantages and drawbacks of both studied imaging techniques are discussed in terms of patient dose reduction and image quality.
1993年在法国一家儿科放射科进行的一项研究中，对使用传统（胶片-屏组合）和光激励磷光板系统进行胸部床边检查时的图像质量和患者接受的剂量进行了比较。该研究纳入了71名年龄在9天至18岁（平均：43个月）之间的儿童（36名男性和35名女性）。通过质量控制程序对所有使用的放射设备的技术性能进行了持续检查。为纳入研究的每位患者拍摄一张传统胶片和三张“光激励”胶片（为“光激励”系统选择的毫安秒乘积逐渐降低至传统技术的60%）。在检查期间，使用热释光氟化锂芯片测量入射表面剂量。由三位独立的放射科医生评估284张胶片（213张“光激励”胶片+71张传统胶片）的图像质量。从降低患者剂量和图像质量方面讨论了两种研究成像技术的优缺点。
