Abstract
An apparatus and method for calibrating an x-ray tube include a computer programmed to acquire a starter voltage/current value corresponding to a width, a length, or a position of a target focal spot capable of being generated by the x-ray tube. The computer is programmed to generate an electron beam and to steer the electron beam based on the starter voltage/current value. The computer is also programmed to steer the electron beam based on a value adjusted from the starter voltage/current value. The computer is programmed to calculate a final voltage/current value that is configured to generate the width, length, or position of the target focal spot based on the starter voltage/current value and the adjusted starter voltage/current value.
