Patent number: 11903691Abstract: A method to automatically align magnetic resonance (MR) scans for diagnostic scan planning includes acquiring a three-dimensional (3D) localizer image of an anatomical object. One or more initial landmarks are identified in the 3D localizer image using a landmarking engine. One or more main axes associated with the anatomical object are identified based on the one or more initial landmarks. The 3D localizer image is registered to a canonical space based on the main axes associated to yield a registered 3D localizer image. The landmarking engine is applied to the registered 3D localizer image to yield one or more updated landmarks. A plurality of reference points for performing a MR scan are computed based on the one or more updated landmarks.Type: GrantFiled: June 19, 2018Date of Patent: February 20, 2024Assignee: Siemens Healthineers AGInventors: Fitsum Aklilu Reda, Yiqiang Zhan, Martin Harder

Patent number: 11826135Abstract: In a method and system for automatically positioning a region of interest of a patient for a medical imaging examination in an isocenter of a medical imaging apparatus, the region of interest of the patient is brought into a patient receiving region of the medical imaging examination for a position-determination measurement, a position-determination measurement is performed to capture position-determination image data, the position-determination image data is analyzed to determine a position of the region of interest of the patient from the position-determination image data, and the patient is automatically positioned such that the position of the region of interest of the patient coincides with the position of the isocenter of the medical imaging apparatus.Type: GrantFiled: September 25, 2020Date of Patent: November 28, 2023Assignee: Siemens Healthcare GmbHInventor: Martin Harder

Patent number: 11061087Abstract: A method includes determining a position of a local coil, a coil position, and a position of a body part of a patient, a body part position. Spacing between the coil position and the body part position is determined. An optimized MR sequence is determined. Based on the determined spacing between the coil position and the body part position, it is checked that in a subsequent MR examination of the patient, a predetermined loading threshold value (e.g., an SAR value) is not exceeded. The optimization of the MR sequence thus takes place under the boundary condition that the loading threshold value is not exceeded.Type: GrantFiled: July 18, 2019Date of Patent: July 13, 2021Assignee: Siemens Healthcare GmbHInventors: George William Ferguson, Martin Harder, Daniel Rinck

Publication number: 20190195977Abstract: Noise information describing general noise properties of a magnetic resonance imaging apparatus (MRIA) in an imaging volume is measured using a predetermined first magnetic resonance sequence. Patient image data is acquired in at least one imaging region of a patient using a predetermined second magnetic resonance sequence. An anatomical landmark of a group of predetermined anatomical landmarks is localized in the patient image data by a landmark detection algorithm. For landmarks, reference information regarding imaging quality information is provided in a database. A landmark-specific signal-to-noise ratio is determined for each localized landmark from the patient image data at the landmark and the noise information, and the imaging quality information is determined from the landmark-specific signal-to-noise ratio.Type: ApplicationFiled: December 22, 2018Publication date: June 27, 2019Inventors: Andre de Oliveira, Martin Harder, Stephan Kannengießer, Wilfried Landschütz

Patent number: 10185018Abstract: A method for automatically updating planning of measurement volumes as a function of object motion during MRI examination of an object in which the planning images a specific subject/object anatomy by MRI, includes defining an object reference pose and a reference coordinate system for the reference pose at a time during MRI examination, with the reference coordinate system being used for planning the measurement volumes. During examination, information is obtained about an object pose change between a current object pose at the time and the reference pose. For each subsequent scan or single acquisition of imaging data during examination, pose change information is used for calculating a new coordinate system for the current pose and updating the planning of measurement volumes as a function of the new coordinate system so the imaged object anatomy remains the same throughout the scans or acquisitions of imaging data irrespective of object motion.Type: GrantFiled: April 18, 2016Date of Patent: January 22, 2019Assignee: Siemens Healthcare GmbHInventors: Thorsten Feiweier, Martin Harder, Tobias Kober

Patent number: 9940713Abstract: A method for MRI inter-scan motion correction includes performing (i) an anatomical localizer scan of a region of interest (ROI) to identify anatomical landmarks defining orientation of a surrounding field-of-view (FOV); (ii) an inter-scan motion reference scan of the ROI to acquire a reference inter-scan dataset indicating a reference navigator location in the ROI; and (iii) scans of the ROI to acquire k-space data. Prior to one or more of the scans, a motion correction process is performed that includes (a) performing an inter-scan motion tracking scan to acquire a tracking inter-scan dataset indicating an updated reference navigator location; (b) determining an estimation of inter-scan patient motion based on a comparison between the reference inter-scan and tracking inter-scan datasets; and (c) updating the FOV relative to the landmarks based on that estimation. Images of the ROI may be generated using the k-space data acquired with each of the scans.Type: GrantFiled: November 15, 2016Date of Patent: April 10, 2018Assignees: Siemens Healthcare GmbH, The General Hospital CorporationInventors: Himanshu Bhat, Keith Aaron Heberlein, Thomas Beck, Martin Harder, Andre Jan Willem Van Der Kouwe, Matthew Dylan Tisdall

Patent number: 9471987Abstract: Disclosed herein is a framework for facilitating automatic planning for medical imaging. In accordance with one aspect, the framework receives first image data of a subject. One or more imaging parameters may then be derived using a geometric model and at least one reference anatomical primitive detected in the first image data. The geometric model defines a geometric relationship between the detected reference anatomical primitive and the one or more imaging parameters. The one or more imaging parameters may be presented, via a user interface, for use in acquisition, reconstruction or processing of second image data of the subject.Type: GrantFiled: July 22, 2014Date of Patent: October 18, 2016Assignee: Siemens Healthcare GmbHInventors: Martin Harder, Yiqiang Zhan, Heiko Meyer, Shu Liao

Patent number: 9055882Abstract: In a method and apparatus to generate a magnetic resonance (MR) image in a volume of interest of an examination subject, the magnetization is excited in an additional volume in the subject by at least one RF pulse, in order to achieve a desired magnetization in the volume of interest. The additional excitation volume differs at least partially from the volume of interest. For this purpose, at least one MR overview image of the examination subject is analyzed automatically to determine a position of at least one anatomical structure of the examination subject, from which the volume of interest is automatically determined. The additional excitation volume is automatically determined using the position of the at least one anatomical structure. The MR image in the volume of interest is acquired with excitation of the magnetization in the automatically determined additional excitation volume.Type: GrantFiled: April 26, 2012Date of Patent: June 16, 2015Assignees: Siemens Aktiengesellschaft, Siemens Medical Solutions USA, Inc.Inventors: Thorsten Feiweier, Martin Harder, John Kirsch, Wilfried Landschuetz, Andreas Schmidt, Katrin Wohlfarth
