(a) MCG signal at D2. The MCG signal has the characteristics of a P wave, QRS wave and T wave group. Twenty-channel MFMs of the (b) Q peak, (c) R peak and (d) T peak. The Y axis and X axis coordinates correspond to the position of the sensor, as shown in Fig. 1. Normal MFM has a single dipole structure. The color depth of the figure represents the intensity of the magnetic field, corresponding to the color bar in the figure.
