Image of FIG. 1.
FIG. 1.

Photograph of the measurement setup from the side. The CSAM is attached to the bottom of the Dewar containing the SQUID sensors. The optical fibers are fed to a control unit outside the shielded room. The Dewar can be positioned freely above the chest of the subject. (Top left inset) Schematic of the CSAM arrangement. Modulation coils around the sensor head allow the measurement of the z-component of the magnetic field.

Image of FIG. 2.
FIG. 2.

Raw MCG signal of a subject detected simultaneously with (a) the CSAM and (b) a SQUID. Averaged MCG signal (200 beats) of the same person measured simultaneously with (c) the CSAM and (d) a SQUID.

Image of FIG. 3.
FIG. 3.

Magnetic relaxation curves of two different nanoparticle concentrations (40 and iron) derived from consecutive measurements by CSAM (solid line) and SQUID sensor (open dots). The inset shows the same data on a log-lin plot.
