PHOTOEMITTER MATRIX X-RAY SOURCE Russian patent published in 2022 - IPC H01J35/02 

FIELD: biomedical diagnostic technologies.

SUBSTANCE: invention relates to the field of biomedical diagnostic technologies. The photocathode matrix is ​​a flat surface made of silicon oxide dielectric with rectangular matrix elements, on each of which film conducting electrodes of indium-tin oxide are formed, connected to periodic interdigitated planar microblades, on which a conductive diamond-like carbon (DLC) nanofilm, containing embedded gold nanostars (GNS) is formed. As a laser light source, a pulsed semiconductor injection laser or a pulsed fiber laser with a nanosecond duration and a wavelength corresponding to the maximum of the plasmon resonance of gold nanostars is used, and a 2D spatial scanner is used as a laser beam scanner.

EFFECT: increasing the spatial resolution of fifth-generation X-ray tomographs, increasing the speed of spatial scanning of an X-ray beam through the use of a matrix emitter and the creation of a durable photoemitter matrix X-ray source for obtaining dynamic spatially scanned X-ray radiation for tomography.
