 Abstract: The lead electromagnetic model (LEM) and the radiofrequency responses, i.e., the net dissipated electrode power and net temperature increase, above background, at the electrodes, were modelled for two coax-type insulated leads with inner and outer helical wires with a pitch of 0.35 mm. The quotient of the variances of the fitted LEM values and observed values (R 2 ) of the radiofrequency responses was substantially different for the lead electrode versus the ring electrode, where R 2 of the ring quotient was a function of the duration of the RF-induced heating.
