摘要： A system for generating a tunable X-ray pulse comprises a first electron beam source configured to direct a first electron pulse of predetermined energy and pulse length towards a first interaction zone, a laser beam source configured to direct a first photon pulse of predetermined energy and pulse length towards the first interaction zone to interact with the first electron pulse. The first interaction produces a substantially monochromatic second photon pulse of higher photon energy directed towards a second interaction zone, and a second electron beam source configured to direct a second electron pulse of predetermined energy and pulse length towards the second interaction zone so that the second interaction produces an X-ray pulse of predetermined energy and pulse length in a cascaded inverse Compton scattering (ICS) configuration.

摘要： A method and apparatus are provided for generating high frequency electromagnetic energy using a secondary emission electron source. An x-ray source is therefore provided having a primary electron emitter, a secondary emission member, and an anode. The primary electron emitter provides a primary electron current directed to the secondary emission member. The secondary emission member then generates a secondary electron current which causes x-ray generation when impinging upon the anode.

The CT imaging system includes a detector array having a plurality of detector elements and an x-ray tube configured to direct an x-ray beam towards the detector through an object to be imaged.
