Patent number: 10238352Abstract: A method for generating x-ray images of an examination object is described. In the method, x-rays are emitted in a direction of an x-ray detector, wherein an examination object is arranged between the x-ray detector and an x-ray source emitting the x-rays. An anti-scatter grid, which is arranged between the examination object and the x-ray detector, is moved across the detection surface of the x-ray detector. X-ray detector signals are acquired with temporal and spatial resolution, the x-ray detector signals including the intensity of the x-rays incident on the x-ray detector. The x-ray detector signals are evaluated taking into account a temporal variation of the acquired intensity of the x-ray detector signals caused by the movement of the anti-scatter grid. An x-ray imaging apparatus is also described.Type: GrantFiled: May 31, 2016Date of Patent: March 26, 2019Assignee: Siemens Healthcare GmbHInventor: Jörg Freudenberger

Patent number: 9842720Abstract: An x-ray tube unit includes an x-ray tube unit housing, in which a vacuum housing is disposed, which includes a high-voltage component. The vacuum housing includes an insulating medium circulating in the x-ray tube unit housing flowing around it. Further, a cathode module and an anode are disposed in the vacuum housing, the cathode module lying at high voltage and including an emitter which emits electrons when heating current is fed to it. In addition, a potential difference is present between the cathode module and the anode for accelerating the emitted electrons. In accordance with an embodiment of the invention a high-voltage feed, a heating transformer and a radiation protection component are integrated into the high-voltage component, the high-voltage component being filled at least partly with an electrically-insulating encapsulation material. This produces a compact and installation-friendly x-ray tube unit which has high operational safety.Type: GrantFiled: January 21, 2015Date of Patent: December 12, 2017Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Jan Berk, Jörg Freudenberger, Ernst Neumeier, Jana Noack, Raimund Schwarz, Lothar Werner
