Up to now, E-field probes have been presented for relative SAR estimation. In this work, an optical dipole-controller system was developed, to measure absolute E-field values. The dipole probe was calibrated in a custom built Crawford TEM cell to assure the accuracy of the measured E-field values. The new probe can determine E-fields between 65 and 643.5 V/m, which could be demonstrated of a known 7 T head coil.
