ABSTRACT:
An upconversion stage for a wireless magnetic resonance imaging system local coil array has a number of upconversion circuits. Each upconversion circuit includes a parametric amplifier, an antenna and a delay line between the amplifier and the antenna. The path length of the delay line in one upconversion circuit differs from the path length of the delay line in an adjacent upconversion circuit by a predetermined amount.
