Magnetic field measurements of the human heart at room temperature
Date:12/11/2009

eter developed by NIST continues to fulfil expectations.

The optical sensor is a byproduct of the development of miniaturized atomic clocks, one of NIST's current key research areas. As biomagnetic research is not established at NIST, the scientists turned to their colleagues at PTB in Berlin. PTB is one of the few metrological state institutes in the world with a large scale biomedical research program. The combination of highly advanced equipment such as the magnetically shielded room (BMSR-2) with the experience in testing new sensors on human subjects made PTB the ideal partner for NIST.

Using the optical magnetometer PTB experts measured the magnetic field of the human heart and relaxation curves of magnetic nanoparticles. Both are important routine laboratory measurements normally applying SQUIDs. For a direct comparison of the results, SQUID reference data were recorded simultaneously with the optical magnetometer using the multichannel SQUID device installed in the BMSR-2.

The impressive quality of the data obtained confirms the suitability of these optical micromagnetometers in the picotesla range. This is the range for magnetic field measurements of the heart, but further improvements are needed to measure the even tinier fields of the human brain. Compared to SQUIDs, the optical sensors exhibited as expected a significantly higher noise level. The distinct advantage of these sensors lies, however, in their small design (< 1 cm3). This allows them to be installed at a small distance from the magnetic source in order to increase the signal strength. The room temperature operation of the sensor and its small size will allow a much simpler system design compared to other sensor types suitable for this measurement range. The fabrication of the sensor by use of microsystem technology could enable simple and cost-effective mass production. NIST plans the development of a multichannel system on the basis of the existing technology. Fu
