  • Publication number: 20210097738
    Abstract: A method for decomposing noise into white and spatially correlated components during MR thermometry imaging includes acquiring a series of MR images of an anatomical object and generating a series of temperature difference maps of the anatomical object. The method further includes receiving a selection of a region of interest (ROI) within the temperature difference map and estimating total noise variance values depicting total noise variance in the temperature difference map. Each total noise variance value is determined using a random sampling of a pre-determined number of voxels from the ROI. A white noise component and a spatially correlated noise component of the total noise variance providing a best fit to the total noise variance values for all of the random samplings are identified. The white noise component and the spatially correlated noise component are displayed on a user interface.

  • Publication number: 20200342591
    Abstract: A method for phase correction in proton resonance frequency (PRF) thermometry application includes acquiring a series of magnetic resonance (MR) images comprising a first MR image and plurality of subsequent MR images depicting an anatomical area of interest. The MR images are acquired while tissue in the anatomical area of interest is undergoing a temperature change. Each subsequent MR image is registered to the first MR image to yield a plurality of registered images. A plurality of basis images are computed from the registered images using Principal Component Analysis (PCA). The basis images are used to remove motion-related phase changes from a second series of MR images, thereby yielding a motion corrected second series of MR images. One or more temperature difference maps are generated that depict a relative temperature change for the tissue in the anatomical area of interest based on the motion corrected second series.

  • Publication number: 20200243090
    Abstract: A system for performing magnetic resonance tomography is disclosed. A control system creates a speech data stream from an acquired linguistic expression and generates a command library, which contains a selection of speech commands, to each of which one or more linguistic expressions are assigned. The selection of speech commands is loaded from a command database depending on a current system status of a magnetic resonance (MR) scanner. The control system applies a speech recognition algorithm to the speech data stream to determine whether a linguistic expression contained in the command library can be assigned to the speech data stream. If so, the acquired linguistic expression is recognized, a speech command from the command library assigned to the recognized linguistic expression is established, and a control command for controlling the MR scanner in accordance with the speech command is created.

  • Patent number: 10702186
    Abstract: In a method and apparatus for identifying an organ structure of an examined object in magnetic resonance image data, magnetic resonance measurement data for the organ structure of the examined object are acquired by operation of a magnetic resonance scanner using a magnetic resonance sequence that specifies a sampling scheme of k-space. Magnetic resonance image data are reconstructed from the magnetic resonance measurement data. The organ structure is identified in the magnetic resonance image data. The sampling scheme of k-space is selected so as to support the subsequent identification of the organ structure in the magnetic resonance image data reconstructed from the magnetic resonance measurement data.

This may include acquiring first image data of an intervention region during a first intervention on the skin of the patient. At least two landmarks may be identified on the skin of the patient on the basis of the acquired first image data. A position of the first intervention is then determined with the aid of the landmarks as reference points. In addition, the position of the first intervention and of the landmarks may be stored in a data memory unit. A position of the second intervention is subsequently localized on the basis of the stored position and of the at least two landmarks.

  • Patent number: 10215823
    Abstract: In order to determine the position of a reception coil in a magnetic resonance (MR) scanner of an MR apparatus, wherein the instrument has a reception coil, MR data are acquired from the reception coil along one direction in the scanner, and are provided to a processor that determines a position specification from the acquired MR data. The processor determines the position specification by initially executing a training period, using a first position specification establishment method, in order to produce a training period dataset, and then the training period dataset is used to establish a final position specification with a second position specification establishment method that differs from the first position specification establishment method.
