  • Publication number: 20070085540
    Abstract: In a method for decoupling an RF transmit coil in a magnetic resonance imaging system, the RF transmit coil has more than one antenna unit and stimulus signals are inputted to said antenna units via connecting cables. A capacitor is connected in series before each of the cables and the value of the series capacitor is such that it just compensates the signal phase shift caused by the connecting cable to zero. Decoupling circuits are connected between said antenna units and before the series capacitors for decoupling said antenna units. The decoupling circuit, by simply employing the decoupling capacitor, decouples the inductive coupling and capacitive coupling between the antenna units simultaneously. The method can be employed to decouple an RF transmit coil outside a magnetic body via the use of a decoupling capacitor.
