Radio frequency (RF) assembly with planar resonator

Abstract

In a radio frequency (RF) assembly for a magnetic resonance examination system, the RF assembly comprises: at least one receiver coil, for receiving MR signals from a patient, at least one low-noise amplifier (LNA), connected to the receiver coil for amplifying the MR signals, at least one low-voltage differential signal (LVDS) connection, wherein the LVDS connection is configured to transmit the received MR signals and to apply electrical power to the LNA, wherein the LVDS connection is formed as a LVDS digital cable (1). A solution for B1 transparency of the coil array, which reduces solder connections and RF plugs is to be achieved. This is achieved by at least one planar resonator (2), wherein the planar resonator (2) is inductively coupled to the LVDS digital cable (1) configured to act as an RF trap (10) for blocking spurious signals on the LVDS digital cable (1).
