Patent ID: 7233645

Claim:
A control system for an X-ray source, comprising: a resonant converter that drives a transformer for operating the X-ray source; a sensor interface operative to receive an X-ray feedback signal indicative of a characteristic of an X-ray flux output by the X-ray source, and to receive, concurrently with the reception of the X-ray feedback signal, an electron beam-accelerating voltage feedback signal indicative of a voltage supplied to the X-ray source by a resonant converter-based power supply that includes the resonant converter; a programmable controller operative to generate, in response to the X-ray and electron beam-accelerating voltage feedback signals, one or more control signals for controlling the X-ray source; and a control interface for supplying the one or more control signals to the X-ray source, either directly or indirectly, wherein a filament power supply switching frequency is synchronized to that of the resonant converter-based power supply.
