Application And Clinical Evaluation Of A Sensitometric System In A Cardiac Catheterization Laboratory

This paper discusses long-term results obtained using sensitometry techniques for monitoring radiograph processing in a cardiac catheterization laboratory. The elema and cine radiographic films are processed automatically in a Profexray and Combilabor processor, respectively. Techniques are described for quality control and reproducibility of both cine and elema radiographs. Comparisons are made of radiographs developed prior to implementation of the sensitometric system and after implementation. Automated continuous temperature monitoring is discussed as an additional tool for recording developer - bath temperature fluctuations. Trouble shooting hints are presented to aid in distinguishing between processor and x-ray equipment as the source of radiographic problems. Suggestions are also provided for implementing a sensitometric system in departments using radiographic films.
