MULTI-CATHODE X-RAY TUBES WITH STAGGERED FOCAL SPOTS, AND SYSTEMS AND METHODS USING SAME

摘要

A source of X-rays including at least two cathodes and at least one common anode configured and arranged so as to generate at least two spaced apart beams of X-rays emanating from respectively different locations of the anode, and separately controlled so as to be generated independently of one another. The staggered focal spots can be generated simultaneously or alternately as required. An X-ray imaging system comprising such an X- rays source, and a method utilizing such a source are also disclosed.
