Patent number: 11523747Abstract: A method for operating a medical diagnostic system that is configured to use a system component of the diagnostic system to generate examination data of a person under examination during an examination procedure is provided. The examination procedure with control of the system component is controlled by a piece of control software, and a component driver exchanges control commands of the control software with the system component in order to control the system component. The method includes providing an event driver that communicates with the control software via an interface of the control software. Via the event driver, a first event is detected in the examination procedure and reported to the event driver. When the first event is detected in the examination procedure, the use of the system component in the examination procedure is modified to a first type defined by the event driver.Type: GrantFiled: January 2, 2020Date of Patent: December 13, 2022Assignee: Siemens Healthcare GmbHInventors: Simon Bauer, Thorsten Feiweier, Christian Köglmeier, Carsten Prinz, Daniel Nicolas Splitthoff, Michael Zenge, Michael Schneider

Patent number: 11353534Abstract: A method for acquiring a magnetic resonance data set of an object under examination by a magnetic resonance system using a scan sequence is provided. The scan sequence includes a succession of sequence blocks, and in each sequence block, there is at least one sub-block including an excitation section and/or a detection section. An excitation section includes at least one excitation pulse, and in a detection section, an echo signal or an echo train is acquired as a scan signal. At least one item of motion information is provided for each sub-block. The motion information contains information about a movement of the object under examination within a duration of the sub-block. Some of the sub-blocks are automatically repeated. At least the sub-blocks having motion information that exceeds a threshold value are repeated. The threshold value defines a motion amplitude.Type: GrantFiled: November 17, 2020Date of Patent: June 7, 2022Assignee: Siemens Healthcare GmbHInventors: Daniel Nicolas Splitthoff, Tobias Kober, Randall Kroeker, Daniel Przioda, Dominik Paul

Patent number: 11249162Abstract: Techniques are disclosed related to the compensation of phase offsets introduced into k-space lines as a result of encoding of blip gradients due when motion is present, which may be used for parallel magnetic resonance imaging (MRI) techniques such as blipped SMS or blipped CAIPIRINHA. The compensation of these additional phase offsets may prevent artifacts that would otherwise be present in the reconstructed images as a result of motion during the MRI scanning procedure. The additional phase offsets may be accounted for during the image acquisition phase of the MRI scan or, alternatively, during the image reconstruction phase.Type: GrantFiled: August 4, 2020Date of Patent: February 15, 2022Assignees: Siemens Healthcare GmbH, The General Hospital CorporationInventors: Daniel Nicolas Splitthoff, Daniel Polak, Kawin Setsompop, Borjan Gagoski
