Phantom experiment. Maximal temperature increases, Δ TMax, measured on DBS electrodes during 3.0T and 1.5T scanning of the ASTM head-and-torso phantom. SARC –average coil SAR displayed by the scanner after patient weight corresponding to auto-prescan TG was entered, SARPM – 6min. average displayed by the power monitor (3.0T).
