Abstract
Methods and systems are provided for dual energy imaging. In one embodiment, a method comprises controlling an x-ray source with a first voltage to generate x-rays at a first energy, controlling the x-ray source with a second voltage to generate x-rays at a second energy lower than the first energy, and controlling a current of the x-ray source to peak above a target current when a voltage of the x-ray source is transitioning from the first voltage to the second voltage. In this way, the duration for transitioning from the first voltage to the second voltage is reduced, thereby enabling faster voltage switching of the x-ray source, improved energy separation in acquired projection data, and improved image quality.
