Abstract: Apparatus and method for a radially attachable RF trap attached from a side to a shielded RF cable. In some embodiments, the RF trap creates a high impedance on the outer shield of the RF cable at a frequency of RF signals carried on at least one inner conductor of the cable. In some embodiments, an RF-trap apparatus for blocking stray signals on a shielded RF cable that has a peripheral shield conductor and a inner conductor for carrying RF signals includes: a case; an LC circuit having a resonance frequency equal to RF signals carried on the inner conductor; projections that pierce and connect the LC circuit to the shield conductor; and an attachment device that holds the case to the cable with the LC circuit electrically connected to the shield conductor of the shielded RF cable.

Abstract: A method and apparatus for transmitting and receiving RF signals suitable for MRI and/or MRS from MR “coils” (antennae) that are arranged in an array next to a tissue-sample-slice holder that constrains the front, back, and edges of the tissue sample and is configured to rotate in a “roll” direction (about an axis parallel to the main DC magnetic field) and optionally also rotate in a pitch direction (at varying angles up and down, left-to-right, or both, relative to the roll axis and thus to the main DC magnetic field); the system optionally includes temperature control (heat and/or cooling), an optical grid that is marked or etched into a cover glass that holds the sample (in some embodiments, the grid is visible in the MRI images as well), an electrical and/or optical stimulation means for delivering stimulation Some embodiments combine optical image data with MR image data.

Abstract: A method and apparatus for receiving (RX) radio-frequency (RF) signals suitable for MRI and/or MRS from a plurality of MRI “coil elements” (antennae), each contained in one or a plurality of body-coil parts, wherein the body-coil parts are easily assemble-able into a body-coil assembly (e.g., in some embodiments, a cylindrical body-coil assembly) with shield elements that are overlapped and/or concentric, and wherein the body-coil assembly is readily disassemble-able for easier shipping, and wherein the body-coil parts are optionally usable individually as transmit (TX) and/or receive (RX) coil elements for MRI. In some embodiments, the system provides for repeatable assembly and disassembly for ease of maintenance (such as frequency tuning and impedance matching) such that the body-coil assembly can be fully assembled and tested, then taken apart for less costly and easier shipping (with reduced risk of damage) and then reassembled at the destination for operation in an MRI system.
