X-RAY SOURCE, COMPUTER TOMOGRAPHY APPARATUS, AND METHOD FOR THE OPERATING X-RAY SOURCE AND THE COMPUTER TOMOGRAPHY APPARATUS

摘要

An X-ray source comprising a laser (12) and a plurality of X-ray emitters (8) each with an electron source (32) and an X-ray emission center (34) disposed in an anode (22), wherein each X-ray emitter (8) is assigned an optical path along which a laser beam (36), emitted by the laser (12) is guided from said laser (12) to the electron source (32) of the X-ray emitter (8). During operation of the X-ray source using this laser beam (36), an electron beam (30) emitted by the electron source (32) is generated and accelerated into the X-ray emission center (34) of the X-ray emitter (8) in order to generate an X-ray beam bundle (20) emitted from the associated X-ray emitter (8), wherein the laser beam (36) is guided over at least a partial length of at least one optical path of an optical waveguide (10).
