Viktor W Pleil is a notable inventor based in Wheaton, IL (US), recognized for his contributions to X-ray technology. With a total of 4 patents, Pleil has made significant advancements in the field, particularly in the design and functionality of X-ray tubes.

Latest Patents

Among his latest patents is the "X-ray tube electron beam switching and biasing method and apparatus." This invention allows an X-ray tube to produce multiple anode spots, enabling the generation of three or more different size anode focal spots without the need for modifications to connectors, cabling, or high voltage supplies. The design incorporates an isolating fiber optic control input that connects an external light-emitting diode to a controller within the tube housing. This controller responds to light signals to control the size of focus spots on the tube anode. In a preferred embodiment, each of the three filaments is individually energized to create three distinct focal spots, while a biased cathode cup adds a fourth spot capability. An alternate embodiment features a split or segmented cathode cup, with segments biased to different electrical potentials, enhancing the tube's versatility. Additionally, confirmation circuitry is included to monitor the controller's operation and deactivate the X-ray tube in case of a malfunction.

Another significant patent is the "Dual filament X-ray tube used in production of fluoroscopic images." This invention provides a beam of X-radiation with rapidly switchable intensity values. The X-ray tube is equipped with one or more thermionic filaments and cathode bias control circuitry that limits electron flow between the cathode and anode structures. The bias control circuitry applies various predetermined negative potentials to the cathode cup, allowing for precise control over the number of electrons reaching the anode. This rapid switching capability is particularly beneficial in fluoroscopic examination systems, where radiation levels need to be adjusted quickly between low and high levels.
