MRI and Spectroscopy Multi-part Body Coil

Technology No. 20170291
IP Status: Issued US Patent; Application #: 16/422,355

MRI Coil Transmits and Receives RF Signals

A multi-part body coil apparatus can transmit (Tx) and/or receive (Rx) radiofrequency (RF) signals suitable for magnetic resonance imaging (MRI) and/or magnetic-resonance spectroscopy (MRS). The coil is configured as either a circularly polarized transverse-electric-magnetic (TEM) coil or a birdcage coil, and is easily assembled, disassembled (e.g., for easier maintenance, testing, tuning and/or shipping) and reassembled. The apparatus consists of one or more body-coil portions, each having a frame with a concave inner face and a convex outer face, at least one RF coil element mounted to the frame, a tune-and-match circuit operatively coupled to the RF coil element, a shield with partially overlapped, staggered conductors on opposite faces of a dielectric substrate (wherein the shield is coupled to the convex outer face of the frame), a mechanism to align each body-coil portion to neighboring portions, and an interconnection circuit configured to transmit to and/or receive from the RF coil elements. Preamplifiers, Tx-Rx switches and power amplifiers may be built into each of the body-coil portions.
