Elimination of coupling between cylindrical transmit coils and surface‐receive coils for <i>in vivo</i> NMR

Abstract

Coupling between large transmit and surface-receive coils is eliminated using a lambda/4 cable, terminated with crossed diodes to ground, inserted between the receive coil and ground, and by using a cable of length a little less than lambda/2 inserted between the transmit match capacitance and the normal crossed diodes in the transmit input line.
