TL;DR: In this paper, a quadrature surface coil array comprising a plurality of single loop surface coils interspersed with adjacent double-loop surface coils, at least some of said surface coils overlapping the ends of adjacent surface coils and having the two loops in series to support only a single current mode was proposed.

TL;DR: In this paper, a radio frequency surface probe for data acquisition in magnetic resonance systems is presented, which is comprised of a plurality of inductors connected together with tuning capacitors in a balanced configuration, enabling the probe to be impedance matched and to resonate at two separate frequencies without having to be tuned between frequency settings.

TL;DR: A balun circuit arrangement for radio frequency (RF) coils in magnetic resonance (MR) systems was proposed in this article, where a conductor having a length equal to a quarter wavelength at the tuned resonance frequency of the RF coil was employed.

TL;DR: In this paper, a system for providing hyperthermic treatment of tumerous tissue using a phased array antenna for focusing radio frequency (RF) energy on the tumorous tissue was proposed, where free induction decay (FID) signals were used to determine the relative phase and amplitude of RF excitations which are to be transmitted by each element of the phase array antenna.

TL;DR: A surface coil for use in MRI data acquisition systems is described in this paper, where the surface coil has the capability of operating as a quadrature coil and of supporting two independent current moles enabling tuning to two separate frequencies.
