  • Publication number: 20210093221
    Abstract: 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.

  • Publication number: 20200025845
    Abstract: 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.

  • Publication number: 20190195977
    Abstract: 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.

  • Publication number: 20190021625
    Abstract: 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.

  • Patent number: 10185018
    Abstract: 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.

  • Patent number: 9940713
    Abstract: 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.

  • Patent number: 9063205
    Abstract: In a magnetic resonance method and apparatus wherein the magnetic resonance device has a movable patient bed, in a first overview measurement, a first image data record of a patient is acquired, and patient information and/or information of a treatment region of a patient is/are determined from the acquired first image data record. In a second overview measurement, dependent on the patient information and/or on the positioning information of the treatment region of the first image data record, a second image data record is acquired. In a planning step a layer planning for the image data acquisition is implemented from the acquired second image data record. Image data for a medical and/or diagnostic issue and/or examination are recorded. The first image data record of the first overview measurement is recorded with a lower spatial resolution than a spatial resolution of the second image data record of the second overview measurement.

  • Patent number: 9055882
    Abstract: 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.
