Study Findings from GE Global Research Broaden Understanding of Plasma Physics (Design and characterization of electron beam focusing for X-ray generation in novel medical imaging architecture)

By a News Reporter-Staff News Editor at Physics Week -- New research on Plasma Physics is the subject of a report. According to news reporting originating in Niskayuna, New York, by VerticalNews journalists, research stated, "A novel electron beam focusing scheme for medical X-ray sources is described in this paper. Most vacuum based medical X-ray sources today employ a tungsten filament operated in temperature limited regime, with electrostatic focusing tabs for limited range beam optics."

The news reporters obtained a quote from the research from GE Global Research, "This paper presents the electron beam optics designed for the first distributed X-ray source in the world for Computed Tomography (CT) applications. This distributed source includes 32 electron beamlets in a common vacuum chamber, with 32 circular dispenser cathodes operated in space charge limited regime, where the initial circular beam is transformed into an elliptical beam before being collected at the anode."

According to the news reporters, the research concluded: "The electron beam optics designed and validated here are at the heart of the first Inverse Geometry CT system, with potential benefits in terms of improved image quality and dramatic X-ray dose reduction for the patient."
