Abstract: An inherently de-coupled sandwiched solenoidal array coil (SSAC) is disclosed for use in receiving nuclear magnetic resonance (NMR) radio frequency (RF) signals in both horizontal and vertical-field magnetic resonance imaging (MRI) systems. In its most basic configuration, the SSAC comprises two coaxial RF receive coils. The first coil of the array has two solenoidal (or loop) sections that are separated from one another along a common axis. The two sections are electrically connected in series but the conductors in each section are wound in opposite directions so that a current through the coil sets up a magnetic field of opposite polarity in each section. The second coil of the SSAC is disposed (“sandwiched”) between the two separated solenoidal sections of the first coil in a region where the combined opposing magnetic fields cancel to become a null.

Abstract: An RF quadrature detection coil for interventional MRI comprises two nested orthogonal coils having generally rectangular shape in profile, each coil providing one “channel” of signal for quadrature detection. Each rectangular coil has two conductor windings and a common side in which the two conductors along that side are displaced apart in a common plane orthogonal to the plane of the coil to form a circular opening. The two individual coils are configured such that their rectangular conductor winding portions lie in planes perpendicular to each other but their arcuate conductor winding portions coincide in the same plane. Four paralleled conductors are arranged around the shared circular opening while two paralleled conductors form the three sides of the rectangular portion of each individual coil.

Abstract: A pair of RF quadrature detection coils are fitted in an open support structure that allows easy diagnostic access to all tissue areas of the human female breast when performing interventional MRI. The open structure dual coil arrangement comprises a flat base and a slightly "V"-shaped bi-planar upper section supported above the lower base section by eight narrow vertical legs. The upper bi-planar section includes two circular openings for accepting the breasts. Four of the support legs are equally spaced at 900 intervals around each breast opening and provide large side-open access areas to the breast tissues via the sides of the support structure. The "V"-shape of the upper portion of the coil support structure increases the gap clearance at both left and right sides of the support structure to further enhance access to the breasts.
