  • MRI coil and MRI apparatus
    Patent number: 6321108
    Abstract: In order to mitigate the feeling of confinement experienced by a subject (patient) and improve the S/N ratio of an MRI coil when used as a head coil, there is provided an MRI coil 10 comprising a pair of opposing coils 1 and 2 whose coil surfaces face each other with an imaging space interposed, and a quadrature coil 3 which has a coil surface orthogonal to the coil surfaces of the opposing coils 1 and 2 and surrounds the imaging space. When the MRI coil 10 is used as a head coil, the quadrature coil 3 is fitted over the eyes of a subject H, and the opposing coils 1 and 2 are positioned near the ears of the subject H.
    Type: Grant
