A quality control program for cine radiography

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.
