1. A field modification device for modifying a transmission field (Tx) and/or a receive field (Rx) used by a magnetic resonance system, wherein the field modification device comprises:
a plurality of resonator elements being inducible by the transmission field (Tx) and/or the receive field (Rx) to resonate, thereby modifying the transmission field (Tx) and/or the receive field (Rx), respectively, wherein a respective resonance frequency and/or resonance phase of a respective resonator element and/or of a respective group of resonator elements is individually controllable; and
device controller configured to individually control the respective resonance frequency and/or resonance phase of the respective resonator element and/or of the respective group of resonator elements, wherein the resonator elements are dynamically controlled by manipulating their resonance frequency and/or resonance phase.
