[Automated x-ray exposure metering systems]. / Sistemy avtomaticheskoi rentgenovskoi éksponometrii.

The authors suggest a classification for the existing systems and instruments intended for automated X-ray exposure metering developed by the Moscow Scientific Production Association "Spektr" and prospective ones. Demonstrate trends in the development of the main performance of these instruments and systems in terms of years and designs. Consider requirements for the performance of X-ray units not only in terms of anode voltage fluctuations but also in terms of time parameters. Review trends in the design of the systems for automatic sampling of filming parameters during angiography.
