We describe a ciné processing quality control program aimed at the consistent production of high quality angiograms. A year's experience with this protocol has demonstrated the difficulty and importance of maintaining a constant on-frame optical density to ensure consistently high quality. We monitored film processing, speed of the emulsion and the automatic brightness control of the angiographic imaging system several times a day. Variations in film speed and their causes observed in our institution demonstrate that parameters other than film processing should be carefully controlled. The cost of applying this protocol is about +190.00/month and it requires no additional personnel. The cost is offset by the improved quality of the angiograms, reduced repeat examinations, and the improved monitoring of the system making for more effective preventative and corrective maintenance.
我们描述了一个旨在始终如一地制作高质量血管造影照片的电影处理质量控制程序。使用该方案一年的经验表明，保持帧上光密度恒定以确保始终如一的高质量既困难又重要。我们每天多次监测胶片冲洗、乳剂速度以及血管造影成像系统的自动亮度控制。在我们机构观察到的胶片速度变化及其原因表明，除了胶片冲洗之外的参数也应仔细控制。应用该方案的成本约为每月190美元，且不需要额外的人员。血管造影照片质量的提高、重复检查的减少以及系统监测的改善所带来的更有效的预防性和纠正性维护抵消了成本。
