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.
Claims10
A method for operating an x-ray tube, comprising the steps of:
- from each of a plurality of different emitters, emitting an electron beam
- that strikes a surface of an anode, each electron beam, upon striking said surface of said anode, causing an x-ray beam to be generated from the surface of the anode, each x-ray beam having an intensity distribution and said x-ray beams, in combination, having a superimposed intensity distribution;
- with a detector, measuring said superimposed intensity distribution;
- and
- supplying the measured superimposed intensity distribution to a processor and, in said processor, optimizing emission of said x-rays from said surface of said anode dependent on said superimposed intensity distribution.
