Four image-intensification tubes are compared with respect to roentgens per minute at the primary screen vs millilamberts at the secondary screen (efficiency). The parameters for the brightness levels from the input x-ray aspect (kilovolts, kvp) of image-intensifier tubes variations in milliamperage and r per minute produce little change in the efficiency of tube operation. However, at either low or high kilovoltage, the ability of the tube to convert x rays into light falls off. No tube tested had both the most responsive input screen and the most responsive output phosphor. This combination would be optimal for peak efficiency. However, in final judgment, the tube with the greatest light output per incident r per minute (efficiency) is the most desirable, regardless of how this effect is produced. The observations indicate that the differing efficiencies between tubes are directly dependent on phosphor screen efficiencies. (auth)
