Abstract (en)

[origin: EP4024435A1] The present invention relates to an X-ray source device and a method of controlling the same and includes emitters formed on an upper surface of a cathode electrode to emit electrons; an anode electrode formed to be spaced apart from the cathode electrode by a preset distance; gate electrodes located between the emitters and the anode electrode and formed by transferring a graphene thin film including at least one layer onto an upper portion of a metal electrode having at least one opening; a focusing lens located between the gate electrodes and the anode electrode and focusing electron beams emitted from the emitters to the anode electrode; and a control module configured to adjust X-ray dose for each position of the subject by performing a two-dimensional matrix control for the emitters and the gate electrodes.
