Method and apparatus to control radiation tube focal spot size |
摘要 |
A method for controlling focal spot size changes of an x-ray source in an imaging system includes measuring focal spot sizes as a function of a plurality of x-ray source operating parameters, determining a calibration table or transfer function utilizing the measured focal spot sizes as a function of the plurality of x-ray tube operating parameters, and utilizing the calibration table or transfer function to control focal spot size variations during operation of the imaging system.
