  • Patent number: 11125847
    Abstract: A method for magnetic resonance fingerprinting with out-of-view artifact suppression includes acquiring MRF data from a region of interest in a subject. The MRF data is acquired using a non-Cartesian, variable density sampling trajectory. The MRF data includes data from within a desired field-of-view and data from outside the desired field-of-view. The method also includes generating a set of coil images based on the MRF data with a field-of-view larger than the desired field-of-view, determining a noise covariance based on the MRF data from outside the desired field-of-view, generating a coil combined image using an adaptive coil combination determined based on the noise covariance, applying the adaptive coil combination to the MRF data to grid each frame of the MRF data and generate MRF data with out-of-view artifact suppression. The method also includes identifying at least one property of the MRF data and generating a report.

  • Patent number: 11119061
    Abstract: The present invention generally relates to a method of using NMR relaxation rates (R2) of water molecules as an indicator of the extent of aggregation of biopharmaceutical formulations. The biopharmaceutical can be evaluated nondestructively without the vial or container being opened or protective seal compromised (i.e., broken). The method is applicable to all biopharmaceuticals and the water signal obtained by magnetic resonance relaxometry is very strong and sensitive because water is used as the solvent and is present in high (>90%) concentrations in every biopharmaceutical formulation.

    Abstract: According to one embodiment, a magnetic resonance imaging apparatus includes imaging control circuitry and processing circuitry. The imaging control circuitry acquires MR signals in accordance with a first pulse sequence set in an imaging protocol. The processing circuitry determines, during MR signal acquisition according to the first pulse sequence, whether or not additional acquisition of MR signals is necessary based on a determination of image quality based on the acquired MR signals, and if necessity of additional acquisition is determined, adds a second pulse sequence for the additional acquisition to the imaging protocol. The imaging control circuitry acquires MR signals in accordance with the added second pulse sequence. The processing circuitry reconstructs an MR image based on the MR signals acquired through the first pulse sequence and the second pulse sequence.

  • Patent number: 11067656
    Abstract: In a method for operating an MRI device, image data is acquired using a spin echo sequence with an additional readout per pulse train for acquiring correction data. By comparing subsequent correction data of later pulse trains to reference data acquired during a first pulse train of the sequence a difference indicating a parameter shift is determined. A corresponding compensation is then automatically determined in dependence on the difference and is applied to a set of predetermined parameters for at least a respective next pulse train and/or to the image data acquired in at least a respective next pulse train of the sequence.

  • Patent number: 11067937
    Abstract: An image forming apparatus includes a power switch, a power supply circuit, a power supply control unit, and a main control unit that sends a control signal to the power supply control unit and allows the power supply control unit to perform the power supply process based on the control signal. The power supply control unit starts to count pressing time as an elapsed time while the power switch is kept pressed. If the pressing time reaches a predetermined time without a change in the control signal, the power supply control unit forcibly starts a power shutdown process. If the control signal changes before the pressing time reaches the predetermined time, the power supply control unit starts the power shutdown process after receiving from the main control unit the control signal requesting for the power shutdown process.
