METHOD AND APPARATUS FOR ACTIVE FILAMENT MANAGEMENT

KIMTRON, INC., Oxford, C...

1. An apparatus for managing current provided to an X-ray tube filament, comprising:a filament current provider circuit configured to provide a voltage to implement an amount of current flow in a filament, the filament current provider circuit comprising:
a voltage supply, at least one filament transformer, and a filament rectifier circuit, wherein the at least one filament transformer comprises two filament transformers, each of the filament transformers for use with a different size of filament, and wherein the filament rectifier circuit is a dual-filament rectifier circuit; and
a current manager circuit configured to:
receive a first signal from the filament current provider circuit indicating the amount of current flow in the filament;
compare the amount of current flow in the filament to a current command; and
transmit a second signal to the filament current provider circuit, instructing the filament current provider circuit to modify the voltage provided to implement the current flow in the filament such that the current flow in the filament matches the current command.
