자동현상 지능화 보충방식의 임상적용에 관한 연구 = A Study on the Clinical Application of Intelligent Replenishment System of Automatic X-ray Film Processor Based on Film Density

다국어 초록 (Multilingual Abstract)

It is required to apply in clinic for intelligent replenishment system of automatic X-ray film processor based on film density. We processed the serial 300 sheets of radiographic film of chest [14×14", HR-C type] and bone [elbow & ankle(8×10"), skull(10×12"), hand & foot(11×14"), pelvis(14×17"), HR-G type, 68, 70, 77, 85 sheets respectively]. We analyzed the characteristic curves, relative speeds, average gradients and base plus fog densities every twenty five sheets. We also evaluated the developer and fixer replenishment volumes every that time. In the chest and bone radiograph, the characteristic curves were little change and the relative speeds, average gradients and base plus fog densities were within the maximum permit limits. The average developer replenishment volumes were about 43ml/sheet and 39ml/sheet respectively. It brings decrease results about 29% in comparison with the conventional replenishment system.
In our experiences, we concluded that the intelligent replenishment system of automatic X-ray film processor based on film density maintains image Quality consistently, decreases also the replenishment volumes.
Therefore, this system will improve economic and environmental effects and solve problems of overs and shorts replenishment volume.
