Document Type and Number:

Japanese Patent JP2602494

Kind Code:

B2

Abstract:

A matching device uses mutual inductance to couple an NMR radio frequency (RF) coil to an RF power amplifier and RF receiver preamplifier. The device includes a matching coil connected to the RF power amplifier and preamplifier and which is positioned between the NMR RF coil and a decoupling shield in a region where RF flux density, produced by the NMR RF coil, is maximum. This ensures effective coupling to the NMR RF coil and provides a means for adjusting the degree of coupling (hence, input impedance) by varying the area of the matching coil available for intercepting the RF flux.
