System and method for magnetic resonance coil actuation

摘要

An apparatus includes a plurality of magnetic resonance (MR) coil elements and a plurality of voltage-actuated switches coupled to the plurality of MR coil elements, each voltage-actuated switch configured to selectively activate a respective MR coil element. The apparatus also includes a voltage source configured to supply a voltage to the plurality of voltage-actuated switches, a control unit coupled to the voltage source, and a plurality of transmission lines coupled to the plurality of voltage-actuated switches and to the control unit and configured to provide an actuation signal from the voltage source to the plurality of voltage-actuated switches. The plurality of transmission lines being free of discrete resistive elements and having a substantially uniform resistivity such that an interaction between the plurality of transmission lines and the plurality of MR coil elements is minimized and thermal dissipation is distributed over a length of each of the plurality of transmission lines.
