This study evaluated quality control (QC) measurements of D-speed film, E-speed film, and xeroradiography under clinical conditions. Automatic and manual (wet-tank) film-processing techniques were assessed. The results of QC tests (speed index, contrast index, and base + fog measurements) indicated that D-speed film and E-speed film react similarly under clinical conditions with regard to speed and contrast when processed automatically. E-speed film had an elevated base + fog measurement over D-speed film in both processing methods. Manually processed D-speed film had a greater contrast than did manually processed E-speed film. Xeroradiography maintained a consistent level of image processing under clinical conditions during this 90-day trial.
本研究评估了临床条件下D速胶片、E速胶片和干板X线摄影的质量控制（QC）测量值。对自动和手动（湿槽）胶片处理技术进行了评估。质量控制测试结果（速度指数、对比度指数和基值+灰雾测量）表明，在临床条件下，D速胶片和E速胶片在自动处理时，在速度和对比度方面反应相似。在两种处理方法中，E速胶片的基值+灰雾测量值均高于D速胶片。手动处理的D速胶片比手动处理的E速胶片具有更高的对比度。在为期90天的试验中，干板X线摄影在临床条件下保持了一致的图像处理水平。
