Abstract
A MAS regulating system for high frequency medical X-ray generator produces a control signal to stop the exposure when the milliamp-seconds delivered by the X-ray tube becomes equal to or greater than a desired maximum amount set by an operator. The system comprises a converter circuit for converting a signal corresponding to a desired MAS value set in by the operator into a first digital signal having a predetermined format. A digital integrator circuit integrates and converts the actual MA current in the X-ray tube to a digital MAS signal corresponding to the actual MAS value of the current in the X-ray tube and in the same predetermined format as the first digital signal. A comparing circuit compares the first and second digital signals and produces a control signal to stop the exposure when the second digital signal is greater than the first digital signal.
