[Frequency-contrast characteristics of an x-ray image intensifier]. / Chastotno-kontrastnaia kharakteristika usilitelia rentgenovskogo izobrazheniia.

To analyze intricate roentgeno-diagnostic complexes the need for application of frequency-contrast characteristics (FCC) is generally acknowledged at present. The paper presents a description of procedures used in an experimental definition and analysis of three-dimensional characteristics of roentgen image amplifiers constructed with a roentgen electron-optic converter serving as a base. As a result of an experiment the FCC of individual components of the amplifier have been determined, critical links in the device educed and the summary FCC of all its channels calculated. Possible ways of improving the parameters of the Soviet-made units are indicated.
