Maximum temperature changes using different RF-transmit coil arrangements at 3T. Dark solid line: electrode tails shorted together; gray dotted line: electrode tails electrically isolated and separated. Horizontal gridlines are always 0.5°C and the horizontal bar indicates the scan period. All data are from a 3T Siemens TIM Trio system. a: Head coil, depth electrode. b: Head coil, grid electrode. c: Body coil, depth electrode. d: Body coil, grid electrode.
