[Controlling of the high-voltage generator in a direct radiography system].

ABSTRACT

A proposal is presented to improve the original complicated control of the exposure parameters in the direct radiography system (DR). The interface circuitry of the high-voltage generator is redesigned using RS-232 serial COM port. The data and signals are transmitted between the personal computer and the high-voltage generator in the serial mode. A program package is designed to realize the control of the exposure parameters of the high-voltage generator in DR on the PC machine. Experiment results have shown that the proposed console operates steadily and it is capable of providing a more convenient operation console for the direct radiography system.
