Abstract

A quadrature RF coil has been developed for 0.3 Tesla permanent MRI systems. The quadrature RF coil is composed of a solenoid coil and a saddle shaped coil. To minimize the coupling ratio between the two coils, each coil is serially connected to a small extra loop. and the small loops are magnetically coupled to each other. By deliberately adjusting relative positions of the small loops, we have decreased the coupling ratio up to -30dB.
