  • Publication number: 20200264254
    Abstract: The invention relates to an MRI apparatus and a method of MRI involving the acquisition of a first and a second MRI image with mutually different orientations between the BO magnetic field and the object to be investigated. For instance, when imaging structures such as a tendon, due to the magic angle effect, this results in a change in image contrast. According to the invention, a coregistration can be performed between the first and the second MRI image. Moreover, the orientation of a structure within the object can be determined on the basis of the different orientations and the image intensity in the first and the second MRI image. The invention further discloses an apparatus for carrying out the method and a method of shimming the BO magnetic field of the apparatus.

  • Patent number: 9269484
    Abstract: An electromagnet comprising a ferromagnetic yoke which comprises a yoke. Mutually opposing first and second pole pieces are provided. The first pole piece is provided with a planar coil having a first side facing the yoke and a second side facing the yoke. A balancing member is arranged on the second side of the planar coil to counterbalance the attractive force between the planar coil and the yoke. The other pole piece may also be provided with a corresponding balancing member.
