  • Patent number: 11971467
    Abstract: A method for free-breathing abdominal magnetic resonance fingerprinting (MRF) includes applying a pilot tone (PT) RF signal in an MRI system environment using a PT RF signal source, acquiring MRF data from a region of interest in subject using free-breathing MRF pulse sequence and acquiring PT navigator signals based on the applied PT RF signal. The PT navigator signals are associated with a plurality of respiratory states and are encoded with acquired MRF data. The method further includes generating images for each of the plurality of respiratory states based on MRF data and the PT navigator signals. For each respiratory state, the generated images for the respiratory state are compared to a respiratory state MRF dictionary associated with the respiratory state to determine tissue property of the MRF data associated with the respiratory state. A quantitative parameter map may be generated for the determined tissue properties for each respiratory state.

    Abstract: A system and method is provided using a nuclear magnetic resonance (NMR) system. The method includes applying an off-resonance radio frequency (RF) pulse using a radio-frequency coil that is spatially inhomogeneous to induce a B1-dependent resonant frequency shift in spins in a subject and, in the presence of the off-resonance RF pulse, applying a frequency-modulated, frequency-selective RF excitation pulse to spatially encode the spins in the subject. The method also includes acquiring NMR data from the subject that is spatially encoded and reconstructing the NMR data to produce a report of internal materials forming the subject.

  • Patent number: 11875509
    Abstract: A method for determining an undersampling error for a magnetic resonance fingerprinting (MRF) pulse sequence includes retrieving a plurality of sets of spatial response functions. Each set of spatial response functions is associated with a tissue type in a reference image and is based on a tissue mask of the reference image for each tissue type. A signal evolution for each tissue type may be generated based on, for example, the MRF pulse sequence, An undersampled image may be generated for each tissue type using the set of spatial response functions and the signal evolutions for the tissue type. At least one quantitative parameter may be determined by comparing an undersampled image series created from the undersampled images to an MRF dictionary. An undersampling error for the MRF pulse sequence may be generated by comparing a quantitative map (or maps) for the quantitative parameter (or parameters) and the reference image.

  • Publication number: 20230368393
    Abstract: The present application provides an automated system and method for improving and generating annotated magnetic resonance (MRI) images based on magnetic resonance fingerprinting (MRF) data. The present disclosure also provides an automated method for generating the automated system for improving annotated MRI images. In some aspects, the method comprises accessing MRF data, MRI data, and images annotated with bulk-pixel labels that identify a tissue class for a group of patients. The annotated images can be used to train a machine learning system based on MRF data. The system can be trained to assign pixel labels to pixels outside the bulk-pixel labels to create an automated system. The automated system provided may be used to determine disease states using MRF data and generate machine-annotated images that include labels that indicate a tissue class. In this way, the present disclosure provides an automated system and method for improving incomplete annotations.

  • Publication number: 20230288512
    Abstract: The present disclosure provides transmit/receive (T/R) systems for NMR or MRI systems. In one configuration, the systems and methods provided herein may use passively-shielded coils that are compatible with low-field operational environment to replace conventional T/R systems and spatial gradient systems. In some configurations, a low-field imaging T/R system is provided that is designed for nuclear magnetic stimulation and local flux sensitivity, while automatically rejecting incident radiant electromagnetic noise. The design advantageously leverages low required frequencies to distribute the pulse synthesis task, yielding a smaller system with easier maintenance and lower cost. The system may include distributed coil nodes that include a primary radiofrequency (RF) coil configured to transmit and receive RF signals and a secondary coil configured to passively shield the primary RF coil.
