Latest Patents

Glenn R James holds a patent for a method aimed at correcting spherical aberration of the electron beam in scanning electron beam CT systems. This invention addresses the issue of spherical aberration, which produces a deleterious halo around the final electron beam spot, leading to a loss of definition in the rendered images. The patent outlines a method to minimize or eliminate this halo by optimizing the axial position of the electron gun cathode and the potential coupled to the washer-shaped positive ion electrode (PIE). This optimization ensures that the contributions to spherical aberrations at the final beam spot effectively cancel each other out, thereby maximizing image definition.
