Abstract
An apparatus and method for an x-ray system includes an x-ray emitter having a first electrode and a second electrode. A high voltage supply is electrically connected to the first electrode. A power supply is electrically connected to the second electrode. A controller electrically connected to the high voltage supply and power supply is configured to provide a predetermined parameter to the second electrode during operation of the x-ray emitter to generate the predetermined dose rate from the x-ray emitter. During operation of the x-ray emitter, at least one operational value of the second electrode corresponding to the predetermined parameter is measured and combined with the predetermined parameter using an algorithm to obtain a modified predetermined parameter to be provided by the controller to the second electrode during a subsequent operation of the x-ray emitter.
