Abstract
A receiver coil array for a magnetic resonance imaging system has an inductive coupling coil incorporated in the middle coil unit of the receiver coil array as its secondary coil, which serves to regulate the frequency and impedance of the middle coil unit. The secondary coil has an output regulation circuit which can output the magnetic resonance signals received by the middle coil unit to increase the number of the coil units in the receiver coil array that receive and output resonance signals while further regulating the frequency and impedance of the middle coil unit. Since this receiver coil array achieves regulation of the frequency and impedance of the middle coil unit and increases the number of the coil units in the receiver coil array that receive and output the resonance signals, it can improve the quality of the signals received by the receiver coil array. Moreover, the design is simple and is easy to achieve.
