ABSTRACT:
In a high field magnetic resonance imaging apparatus and a method for obtaining signals having a high signal-to-noise ratio with the receiving coil thereof, the apparatus has at least a basic magnet and a receiving coil, the basic magnet generating a basic magnetic field, and the receiving coil being disposed within the basic magnetic field and forming an accommodating cavity. The accommodating cavity of the receiving coil is perpendicular to the direction of the basic magnetic field and is positioned in the field of view of the apparatus. The receiving coil is a loop type coil. The apparatus can further have a bracket for fixing the receiving coil. In the method, a receiving coil is used to receive signals in a magnetic field, wherein the receiving coil is perpendicular to the direction of the magnetic field. By using the apparatus and the corresponding method since the receiving coil can have a loop type design, the signal-to-noise ratio is increased. Moreover, the receiving coil can be disposed at a position closer to the center of the field of view, so that the imaging quality is improved.
