As each research team involved in fetal magnetocardiography has a different measuring system at their disposal that is located in different surroundings, the optimal signal processing will be different too. In the next section, some signal-processing procedures will 22 Maria J. Peters et al. A) B) 0 10 20 30 40 50 60 Time [sec] Figure 13. An example of the filtering procedure. A) The raw signal.

A template of the PQRST-complex is created by averaging the individual PQRST-complexes. The template is then modified by flattening the baseline, which is done by fitting a linear function in the first and last 15 ms of the interval in which the PQRST-complex is located. The position of the Fetal Magnetocardiography 25 R-peak is then corrected by making a cross correlation of each complex with the template. After these corrections, baseline corrections are made in each complex. The complexes that do not resemble the template based on a residue measure are rejected.

In addition, there are more periodic disturbances to consider, for instance, those from computer monitors, motors, vacuum pumps, ventilation systems or traffic. To appreciate the magnitude of environmental disturbances relative to the fetal MCG, see Fig. 2. 2) When measuring a fetal MCG, metallic objects worn by the mother give rise to disturbances. For instance, a watch generates a magnetic field of the order of 10−9 T. Also a hook o f a bra that moves due to breathing may lead to a magnetic field contribution.
