Abstract
An x-ray tube has a number of emitters that generate respective electron beams, and has a common anode at which the electron beams strike on a surface to generate x-rays. A high x-ray dose power with a long lifespan are achieved while being able to quickly vary the x-ray dose power by using a superimposed intensity distribution from the x-ray beams, which is measured by a detector, to optimize the x-ray beams on the surface.
