摘要

由于在敏感的Tx/Rx DF内存在ECG电极材料而产生的不必要的MPI信号，以及由25 kHz DF激发场引起的ECG信号扰动，对于两种电极类型都没有检测到。然而，在电极类型[A]的情况下，观察到的最高电极温度为48.8°C (c.f.图1左)，而在电极类型[B]的情况下，检测到的温度超过115°C (c.f.图1右)。

ECG signal acquisition within a continuous LF powered region

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].
