中文摘要	To improve the efficiency of the flat RF transmit coils, a quadrature coil is designed. The structure is optimized to achieve the best efficiency while the RF magnetic field is kept homogeneous in the imaging volume and drops off quickly outside the imaging volume. To reduce the loss of the coil, some experiments were carried out to determine the cross-section of conductors and the position of the tuning points. A p-type circuit is used to eliminate the electromagnetic coupling between unit coils. A prototype quadrature coil was constructed for a 0.3 T permanent magnet open MRI system, and the experimental results of the decouple circuit are presented.
