Patent number: 10991539Abstract: The X-ray tube disclosed herein includes an electron emission unit including an electron emission element using a cold cathode; an anode unit disposed opposite to the electron emission unit, with which electrons emitted from the electron emission unit collide; and a focus structure disposed between the electron emission unit and a target unit disposed on a surface of the anode unit that is opposed to the electron emission unit. The electron emission unit is divided into a first region and a second region which can independently be turned ON/OFF. The X-ray tube is focus-designed such that collision regions, at the anode unit, of electron beams emitted from the respective first region and second region substantially coincide with each other.Type: GrantFiled: March 29, 2017Date of Patent: April 27, 2021Assignee: NANO-X IMAGING LTD.Inventors: Hidenori Kenmotsu, Hitoshi Masuya, Koichi Iida

Patent number: 10741353Abstract: A robust cold cathode uses an electron emitting construct design possibly for an x-ray emitter device. The electron beam emitted by the emitting construct is focused and accelerated by an electrical field towards an electron anode target. A shield is provided to prevent a cold cathode from being damaged by ion bombardment in high-voltage applications and a non-emitter zone may provide a robust ion bombardment zone. The system is further configured to provide an angled target anode or a stepped target anode to further reduce the ion bombardment damage.Type: GrantFiled: March 25, 2019Date of Patent: August 11, 2020Assignee: NANO-X IMAGING LTDInventors: Hidenori Kenmotsu, Hitoshi Masuya, Koichi Iida

Patent number: 10269527Abstract: An electron emitting construct design of an x-ray emitter device is disclosed configured to facilitate radiation in the X-ray spectrum and further relates to preventing a cold cathode from being damaged by ion bombardment in high-voltage applications. The electron beam emitted by the emitting construct is focused and accelerated by an electrical field towards an electron anode target operable to attract electron beam to an associated focal spot, wherein the generated ions are accelerated along a trajectory perpendicular to the electric field in parallel to the surface of the electron anode target. More specifically, the present invention relates to realizing a robust cold cathode to avoid ion bombardments damages in high-voltage applications, by means of setting non-emitter zone surrounded by or set between the emitter areas. The system is further configured to provide an angled target anode or a stepped target anode to further reduce the ion bombardment damage.Type: GrantFiled: November 26, 2014Date of Patent: April 23, 2019Assignee: NANOX IMAGING PLCInventors: Hidenori Kenmotsu, Hitoshi Masuya, Koichi Iida
