摘要： The present subject matter relates to systems and methods for temporal multiplexing x-ray imaging of dynamic objects with high temporal resolution and fast imaging speed. A pulsed x-ray beam can irradiate an object undergoing a range of motion such as a cyclic motion. Multiple x-ray images can be acquired at different phases within a single motion cycle or range of the object. The multiple x-ray images can be demultiplexed to produce an individual phase image. Compared to sequential imaging, temporal multiplexing x-ray imaging can achieve high temporal resolution of dynamics object in multiple phases with imaging time comparable to that of a single phase. Temporal multiplexing x-ray imaging can thus be applied to a wide variety of applications, including biomedical imaging and industrial non-destructive testing.

摘要： A structure to generate x-rays has a plurality of stationary and individually electrically addressable field emissive electron sources with a substrate composed of a field emissive material, such as carbon nanotubes. Electrically switching the field emissive electron sources at a predetermined frequency field emits electrons in a programmable sequence toward an incidence point on a target. The generated x-rays correspond in frequency and in position to that of the field emissive electron source. The large-area target and array or matrix of emitters can image objects from different positions and/or angles without moving the object or the structure and can produce a three dimensional image. The x-ray system is suitable for a variety of applications including industrial inspection/quality control, analytical instrumentation, security systems such as airport security inspection systems, and medical imaging, such as computed tomography.

摘要： A field emission ion source has nanostructure materials on at least an emitting edge of the anode electrode. Metal is transferred from a metal reservoir to the emitting edge of the anode, where the metal is transferred to an emitting end of the nanostructure materials and is ionized under an applied electric field. Plural ion sources can be combined to form a field emission ion source device. The numbers of emitting sources are selectable through electric or mechanical switches and different ion extraction potentials can be applied. Various nanostructure materials include: single wall carbon nanotubes and bundles, few-walled carbon nanotubes and bundles, multi-walled carbon nanotubes and bundles, and carbon fiber. Nanostructure-containing material is integrated into the anode by electrophoresis, dielectrophoresis, CVD, screen printing, and mechanical methods. Metal, preferably alkali metal, is transferred into the nanostructure-containing material by one or a combination of following intercalation methods: vapor transport, solution, electrochemical, and solid state reaction.

摘要： The invention provides improved devices containing adherent carbon nanotube films, in particular electron field emitter structures containing such films. Previously, attaining even moderate adherence of powdery or mat-like nanotubes to a substrate was difficult, because of the perfect fullerene structure of nanotubes, which tend to exhibit no dangling bonds or defect sites where chemical bonding to the substrate is able to occur. The invention overcomes these problems, and provides a strongly adherent nanotube film, by a variety of fabrication processes.

摘要： An x-ray imaging system has an x-ray source having an electron field emission source that emits an x-ray beam that strikes an elongated, stationary anode in an evacuated housing. A magnetic deflection system steers the electron beam between the electron field emission source and the anode, so that the electron beam can strike the anode at different locations, thereby causing x-rays to be emitted from those different locations, by controlling the degree of magnetic deflection. A radiation detector detects the x-rays after attenuation by an examination subject, and generates signals dependent on the detected radiation that represent an image of the subject.
