The results of a program of quality control on about 30 tomographic and fluoroscopic radiological equipments in the Radiological Departments of Spedali Civili (Brescia, Italy), are reported; the physical performances of the beams (kVp, emission, linearity and reproducibility, HVL, focal spot size) and the geometrical conditions (alignment and beam size, thickness of cut for tomography, resolution and homogeneity) have been verified. During one month we have also verified the working conditions for two automatic film processing systems. Three commercial quality control equipments have been employed and tested. Our results recommend a periodic control of physical and geometrical performances (particularly kVp, emission and beam alignment) and a daily control of the working conditions for the film processing systems. The three quality control systems have given results each other comparable.
报告了对意大利布雷西亚市斯皮塔利奇维利医院放射科约30台断层扫描和荧光透视放射设备进行质量控制计划的结果；已对射线束的物理性能（千伏峰值、发射、线性和再现性、半值层、焦点尺寸）和几何条件（对准和射束尺寸、断层扫描的切割厚度、分辨率和均匀性）进行了验证。在一个月的时间里，我们还对两个自动胶片冲洗系统的工作条件进行了验证。使用并测试了三种商用质量控制设备。我们的结果建议定期控制物理和几何性能（特别是千伏峰值、发射和射束对准），并每天控制胶片冲洗系统的工作条件。这三种质量控制系统给出的结果相互可比。
