摘要： A Magnetic Resonance Imaging (MRI) system is disclosed. The MRI system includes a cryogenic magnet assembly with a cryogenic vessel housing a superconducting magnet. Disposed radially inboard of the cryogenic magnet assembly are a gradient coil module and a plurality of room temperature steel rings proximate to the gradient coil module. A field of view is defined by at least the superconducting magnet, the gradient coil module, and the plurality of room temperature steel rings. In response to the superconducting magnet being energized, the room temperature steel rings create high order harmonics that serve to expand the magnetic field homogeneity FOV, and low order harmonics that tend to degrade the magnetic field homogeneity within the FOV. The low order harmonics are compensated for by the cryogenic magnet assembly.

摘要： Systems, methods and apparatus are provided through which in some embodiments a magnetic resonance imaging (MRI) system includes an asymmetrical magnet to generate an asymmetrical stray field that is particularly well suited to imaging limbs. In some other embodiments, a MRI system includes a conically-shaped casing that allows a patient to more readily access a field-of-view (FOV) in the interior of the MRI system during imaging of limbs. In some embodiments, a MRI system includes a stepped inner bore that has a stepped shape that focuses the FOV in an inner bore of the MRI system on a smaller area that is closer to where a patient accesses the FOV in the MRI that is particularly well suited to imaging a limb in the FOV.

摘要： In some examples, a portable data terminal (PDT) is configured to vibrate when it is installed in a base (e.g., of a docking station), which may help improve the electrical contact between the PDT and the base. For example, when the PDT is installed in a base and subsequently vibrated, the electrical contacts of the PDT may vibrate against opposing electrical contacts in the base, which may help remove contaminants, such as dirt and other debris, from between the electrical contacts of the PDT and the base.

摘要： A shim coil design technique determines a position and a geometry of a room temperature (RT) shim coil to provide both a desired field homogeneity and a desired B0 field setting time. The simultaneous satisfaction of both field homogeneity and field settling time is achieved without a reduction of flux leakage from the shim coil, modification of main magnet protection circuitry, and without necessarily decoupling of the shim coil from the overall main magnet.
