Claim 12:
13. An image processing method, comprising:
controlling an X-ray tube peak voltage of an X-ray radiation source to switch between at least two different X-ray tube peak voltages during a kVp switched spectral scan; and
controlling a grid voltage of the X-ray radiation source to follow the X-ray tube voltage peak during the spectral scan based on a predetermined mapping between X-ray tube peak voltages and grid voltages for a particular focal spot size in order to maintain the particular focal spot size throughout the spectral scan, wherein the mapping is between X-ray tube peak voltages and grid voltages for each respective focal spot size of a plurality of focal spot sizes.
