Patent number: 11964644Abstract: A method for operating a motor vehicle brake system having hydraulic wheel brakes; an atmospheric pressure pressure medium reservoir; a pressure modulation unit setting wheel-specific brake pressures, an electrohydraulic pressure provision device connected to the pressure modulation unit and the pressure medium reservoir which outputs brake system pressure to the pressure modulation unit and draws in pressure medium from the reservoir; a first and second pressure activation valve connecting the pressure provision device to the pressure modulation device. A piston of the piston-cylinder arrangement separates two pressure spaces from one another. A pressure build-up occurs in the first pressure space during a backward movement of the piston and in the second pressure space during a forward movement of the piston. During a brake pressure build-up by a forward stroke of the piston, the activation valve is opened and the first pressure space is hydraulically separated from the pressure medium reservoir.Type: GrantFiled: December 20, 2017Date of Patent: April 23, 2024Assignee: Continental Teves AG & Co.

Patent number: 11207029Abstract: Embodiments provide a method for denoising time series images of a moved structure for a medical device. A movement detector detects the moved structure. The movement detector obtains a measurement of the similarity of two images that each represent the same section of the moved structure. The two images originate from two different time series images. A ratio between spatial and temporal denoising is defined for the section as a function of the measurement of the similarity.Type: GrantFiled: April 4, 2017Date of Patent: December 28, 2021Assignee: Siemens Healthcare GmbHInventors: Stefan Böhm, Boris Stowasser

Patent number: 11096759Abstract: Operating a medical image recording device in the context of an image recording routine for a patient is provided. The image recording routine serves an image recording purpose. The image recording device is controlled based on operating parameters implemented by a controller of the image recording device. The operating parameters are identified completely automatically by an identification algorithm from input data describing at least the patient in the form of a patient model and/or the image recording purpose, and from a registration of the patient with a coordinates system of the image recording device. The operating parameters are used to control the image recording device. An examination region that is to be recorded for the patient and the image recording purpose are derived based on the registration.Type: GrantFiled: June 15, 2019Date of Patent: August 24, 2021Assignee: Siemens Healthcare GmbHInventors: Martin Spahn, Philipp Bernhardt, Stefan Böhm, Boris Stowasser, Richard Obler, Stanislav Tashenov, Rudolf Leiblein, Andreas Berting, Markus Lendl, Oliver Baruth

Patent number: 11004184Abstract: The disclosure relates to a method and an imaging device for generating a new roadmap image of a target object. For the method, a first subtraction image is generated from a first mask image and a contrast agent image of the target object. A parameter value of a parameter of the imaging device that affects the acquisition of images by the device is then changed. A third mask image of the target object is acquired automatically by the imaging device using the changed parameter value. From a second examination image subsequently acquired using the changed parameter value, a third subtraction image is generated by subtraction of the third mask image. The new roadmap image is generated using the first subtraction image and the third subtraction image.Type: GrantFiled: July 1, 2019Date of Patent: May 11, 2021Assignee: Siemens Healthcare GmbHInventors: Stefan Böhm, Philipp Bernhardt, Andreas Berting

Patent number: 9545234Abstract: A method to optimally set a position of a form filter in an x-ray image recording apparatus is proposed. The x-ray image recording apparatus has an x-ray radiation source and an x-ray radiation detector. An x-ray image is firstly recorded in a first position of the form filter. A new position of the filter is then calculated and automatically set with the aid of the x-ray image. A new x-ray image is then recorded. With a minimal dose of a patient, the method enables low contrast images to be recorded for a minimal main dose of the patient, in particular in a sequence.Type: GrantFiled: May 22, 2012Date of Patent: January 17, 2017Assignee: SIEMENS HEALTHCARE GMBHInventors: Philipp Bernhardt, Stefan Böhm, Richard Obler
