Patent ID: 7366283

Claim:
An x-ray system comprising: an x-ray emitter including a first electrode and a second electrode; a high voltage supply electrically connected to the first electrode; a power supply electrically connected to the second electrode; a controller to control the high voltage supply and power supply to provide a predetermined dose rate from the x-ray emitter, the controller being configured to provide a predetermined parameter to the second electrode during operation of the x-ray emitter to generate the predetermined dose rate; wherein 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; and the at least one operational value from a flawed operation of the x-ray system is disregarded and the modified predetermined parameter is the modified predetermined parameter from a previous operation of the x-ray system.
