Abstract
A passive magnetic flux focusing element having electrically conductive wires () or faces () containing an outer area defined by an outer (), an inner () and connecting edges () forming a closed current loop enclosing a surface area penetrated by a time varying magnetic field flux and through induction sets up a time varying electrical current in the conducting loop thereby achieving a counter magnetic field to the penetrating field completely canceling the penetrating field in the interior of the loop, is characterized in that the element is part of an RF volume- or surface-coil arrangement adapted for receiving and/or transmitting RF signals. Such elements increase the sensitivity and the SNR in MRI and MR spectroscopy experiments due to an increased magnetic flux density by means of Lenz lenses, in combination with a conventional probe.
