  • System of Electric Coils for Transmitting and Receiving Radio-Frequency Magnetic Fileds in a Magnetic-Resonance Imaging Apparatus, and Magnetic-Resonance Imaging Apparatus Provided with Such a System of Electric Coils
    Publication number: 20080054903
    Abstract: The invention relates to a magnetic resonance imaging (MRI) apparatus comprising an electrical coil system (17) for transmitting and receiving a radio-frequent (RF) magnetic field from an examination volume (3) of the MRI apparatus. The electrical coil system (17) comprises at least one surface coil (35) which substantially extends in a plane. The surface coil serves for transmitting and/or receiving an RF magnetic field which is substantially oriented perpendicular to the plane of the surface coil (35). The surface coil (35) has a main coil axis (37). When the MRI apparatus is in use the main coil axis (37) extends substantially parallel to a main magnetic field in the examination volume (3) of the MRI apparatus. On both sides of the main coil axis (37) the surface coil (35) comprises an electrically conducting element (39) which extends substantially parallel to the main coil axis (37).
