  • (3-n) dimensional determination of electric conductivity
    Patent number: 11353532
    Abstract: The invention relates to a magnetic resonance imaging system (100) for determining an approximation (150) of an electric conductivity distribution within a three-dimensional anatomical structure of interest. The determining comprises acquiring a first set of (3-n)-dimensional magnetic resonance data (144), reconstructing a (3-n)-dimensional phase distribution (146) using the (3-n)-dimensional magnetic resonance data (144), calculating a (3-n)-dimensional electric conductivity distribution (148) using spatial derivatives within the (3-n) dimensions and applying to the (3-n)-dimensional electric conductivity distribution (148) a scaling factor compensating for the relative reduction of dimensions by n.
    Type: Grant
    Filed: March 11, 2019
    Date of Patent: June 7, 2022
    Assignee: Koninklijke Philips N.V.

  • Radio frequency coil-array for magnetic resonance examination system
    Patent number: 10641851
    Abstract: A radio frequency (RF) coil array with multiple RF coil elements for a magnetic resonance examination system is disclosed. The decoupling of RF coil elements involves sets (pairs) of transformers and may also include geometrical overlap of adjacent coils. The mutual coupling between the transformers is adjustable. This provides additional degrees of freedom to fully decouple the RF coil elements from each other.
