MAGNETIC RESONANCE VOLUME COIL WITH MULTIPLE INDEPENDENT TRANSMIT RECEIVE CHANNELS

摘要

An ultra-high field radio-frequency (RF) coil apparatus for magnetic resonance (MR) systems, may include: a dipole-array based volume coil (2) with a plurality of straight dipole antennas (3); at least three circular conducting rings (4, 5, 6) radial surrounding the dipole-array based volume coil (2), the at least three circular conducting rings (4, 5, 6) being substantially parallel with each other, having a plurality of ports (9, 10) for receiving a set of quadrature drive signals, the RF coil apparatus further comprising at least two independent transmit/receive (T/R) RF channels (11, 12, 13, 14) for driving the dipole-array based volume coil (2) and the at least three circular conducting rings (4, 5, 6).
