  • Magnetic resonance imaging apparatus with spirally extended monopole antenna structure
    Patent number: 10488474
    Abstract: Disclosed is a magnetic resonance imaging (MRI) apparatus with a spirally extended monopole antenna structure whereby magnetic field homogeneity is improved. The apparatus includes: a cylinder body 110; a plurality of monopole antennas forming an array, the antenna being spirally arranged along a surface of the cylinder body 110 at a predetermined inclination angle relative to a central axis of the cylinder body 110; a ground plate 130 in which ends of the monopole antennas are arranged on one surface of the ground plate 130 in a circular arrangement; and a plurality of coaxial cables 140 in which signal lines thereof are respectively connected to the monopole antennas and ground lines thereof are connected to the ground plate 130.
