摘要： An optic device, system and method for imaging are described. The optic device includes a first solid phase layer having a first index of refraction with a first photon transmission property and a second solid phase layer having a second index of refraction with a second photon transmission property, the solid phase layers being situated between an output face and a non-flat input face. The first and second layers are conformal to each other. The imaging system includes a source of electrons and a target, with an array of the optic devices coupled thereto to form limited cone beams of X-ray radiation.

摘要： The subject matter disclosed herein relates to X-ray imaging systems, and more specifically to digital X-ray imaging systems. In one embodiment, an imaging system includes an X-ray source configured to emit X-rays. The imaging system also includes an X-ray detector configured to detect the emitted X-rays and produce a corresponding electrical signal. The imaging system also includes a gantry configured to at least partially revolve the X-ray source and the X-ray detector about a primary rotational axis. The X-ray detector is coupled to the gantry so that a diagonal of the X-ray detector is oriented substantially perpendicular to the primary rotational axis.

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.
