ECG signal acquisition within a continuous LF powered region

Abstract

Neither unwanted MPI signals due to the presence of ECG electrode material within the sensitive Tx/Rx DF nor ECG signal perturbations caused by the 25 kHz DF excitation field have been detected for either electrode type. However, in case of electrode type [A] the maximum observed electrode temperature was 48.8 °C (c.f. Fig 1 LEFT) whereas a temperature of more than 115 °C (c.f. Fig. 1 RIGHT) has been detected in case of electrode type [B].
