X-RAY GENERATION TUBE, X-RAY GENERATION APPARATUS, AND RADIOGRAPHY SYSTEM

摘要

An X-ray generation tube (102) includes: an anode (103) including a target (1) arranged to generate X-rays under irradiation of electrons, and an anode member (2) electrically connected to the target (1); a cathode (104) including an electron emitting source (9) arranged to emit an electron beam (10) in a direction towards the target (1), and a cathode member (8) electrically connected to the electron emitting source (9); and an insulating tube (4) extending between the anode member (2) and the cathode member (8). The anode (103) further includes an inner circumferential anode layer (3) electrically connected to the anode member (2), the inner circumferential anode layer (3) extending along an inner circumferential face of the insulating tube (4), and is spaced apart from the cathode member (8).
