Monitoring of film processors performance is essential since image quality, patient dose and costs are influenced by the performance. A system for sensitometric constancy control of film processors and their associated components is described. Experience with the system for 3 years is given when implemented on 17 film processors. Modern high quality film processors have a stability that makes a test frequency of once a week sufficient to maintain adequate image quality. The test system is so sensitive that corrective actions almost invariably have been taken before any technical problem degraded the image quality to a visible degree.
监测胶片冲洗机的性能至关重要,因为图像质量、患者剂量和成本都会受到其性能的影响。本文描述了一种用于胶片冲洗机及其相关组件的感光测定稳定性控制的系统。文中给出了该系统在17台胶片冲洗机上实施3年的经验。现代高质量的胶片冲洗机具有稳定性,使得每周进行一次测试频率就足以维持足够的图像质量。该测试系统非常灵敏,以至于在任何技术问题将图像质量降低到可见程度之前,几乎总是能够采取纠正措施。
