Abstract:
1. A magnetic resonance imaging system comprising: a transmit-only antenna comprising at least two saddle quadrature antennas connected with each other to form a ring shape, one of the connections being a joint and the remaining connections being formed in an overlapping fashion; and a receive-only phased array antenna comprising a plurality of receive-only antennas connected with each other to form a ring shape, one of the connections being a joint and the remaining connections being formed in an overlapping fashion, wherein an inner diameter of the receive-only phased array antenna is shorter than that of the transmit-only antenna, and the receive-only phased array antenna is coaxially disposed inside the transmit-only antenna with a predetermined gap, wherein each pair of the saddle quadrature antennas are overlapped with each other so that the phase difference between said pair becomes 90°.
