Abstract:
1. An x-ray system comprising: an x-ray source having a focal spot wobbleable between a first position and a second position a scintillator configured to receive x-rays that pass through an object, the x-rays emitted from the x-ray source; a light conversion element designed to convert light released by the scintillator to electrical charge, the light conversion element configured to generate a first electrical charge from a first light quantity corresponding to light released by the light conversion element when the focal spot is positioned at the first position, and configured to generate a second electrical charge from a second light quantity corresponding to light released by the light conversion element when the focal spot is positioned at the second position; a first charge storage device connected via one or more switches to the light conversion element and configured to integrate the first electrical charge; and a second charge storage device connected via the one or more switches to the light conversion element and configured to integrate the second electrical charge.
