  • Patent number: 11467238
    Abstract: Systems and methods for generating images with a magnetic resonance imaging (“MRI”) system, in which the images have been corrected for receive coil nonuniformities are described. Improved data acquisition schemes for fat saturation are also described.
    Type: Grant
    Filed: June 3, 2019
    Date of Patent: October 11, 2022
    Assignees: Mayo Foundation for Medical Education and Research, Siemens Healthcare GmbH

  • Patent number: 11448718
    Abstract: The present disclosure is directed to systems and methods for visualizing low-intensity pathologies or anatomical structures. The method can include applying, via a MRI machine, an RF pulse configured to suppress the imaging of fat in the subject and acquiring, via the MRI machine, an image of the subject. A subtle intensity graduating homomorphic transform is applied to the acquired image to provide improved visualized of the low-intensity pathology or anatomical structure. The resulting transformed image can be output to the user.

  • Patent number: 11275139
    Abstract: Systems and methods for determining proton spectral characteristics associated with a pair of targets from an MRI data volume are provided. The methods can include identifying spectral widths and peak-to-peak distance associated with the targets from the MRI data volume. The targets could include water and fat. The identified proton spectral characteristics can be useful for accurate spectral fat saturation, improving dynamic shim routines, and optimizing bandwidth of radiofrequency pulses used in multi-slice or multi-band excitation.

  • Patent number: 10788970
    Abstract: A system comprises presentation of a user interface on the display for inputting a first set of parameter values for a magnetic resonance scan, reception of the first set of parameter values for the magnetic resonance scan from a user via the displayed user interface, and automatic determination, based on the first set of parameter values, of first additional parameter values for the magnetic resonance scan.

  • Patent number: 10324594
    Abstract: A system for generating medical image scanner configurations includes a scanner configuration database and a simulation component. The database stores a scanner configuration dataset corresponding to a medical image scanner. The simulation component includes a display module which is configured to present a graphical user interface (GUI) utilized by the medical image scanner, and an editing module which is configured to create a modified scanner configuration dataset based on commands received from a user via the GUI. Additionally, the simulation component includes a simulation module which is configured to (i) perform a simulation of the medical image scanner using the modified scanner configuration dataset to yield simulated results, (ii) use the display module to present the simulated results in the GUI, and (iii) in response to receiving user approval of the simulated results via the GUI, save the modified scanner configuration dataset to the database.

  • Patent number: 10074037
    Abstract: Systems and methods for determining optimized imaging parameters for imaging a patient include learning a model of a relationship between known imaging parameters and a quality measure, the known imaging parameters and the quality measure being determined from training data. Optimized imaging parameters are determined by optimizing the quality measure using the learned model. Images of the patient are acquired using the optimized imaging parameters.
