According to certain embodiments, an electron emitter includes a tip with a planar region having a diameter in a range of approximately (0.05-10) micrometers. The electron emitter tip is configured to release field emission electrons. The electron emitter further includes a work-function-lowering material coated on the tip.
Abstract:
Methods of producing microrods for electron emitters and associated microrods and electron emitters. In one example, a method of producing a microrod for an electron emitter comprises providing a bulk crystal ingot, removing a first plate from the bulk crystal ingot, reducing a thickness of the first plate to produce a second plate, and milling the second plate to produce one or more microrods. In another example, a microrod for an electron emitter comprises a microrod tip region that comprises a nanoneedle that in turn comprises a nanorod and a nanoprotrusion tip. The microrod and the nanoneedle are integrally formed from a bulk crystal ingot by sequentially: (i) removing the microrod from the bulk crystal ingot; (ii) coarse processing the microrod tip region to produce the nanorod; and (iii) fine processing the nanorod to produce the nanoprotrusion tip.

Abstract:
Described here is a method for performing phase contrast imaging using an array of independently controllable x-ray sources. The array of x-ray sources can be controlled to produce a distinct spatial pattern of x-ray radiation and thus can be used to encode phase contrast signals without the need for a coded aperture. The lack of coded aperture increases the flexibility of the imaging method. For instance, because a fixed, coded aperture is not required, the angular resolution of the imaging technique can be increased as compared to coded-aperture imaging. Moreover, the lack of a radioopaque coded aperture increases the photon flux that reaches the subject, thereby increasing the attainable signal-to-noise ratio.
