| Abstract: | We have developed a room-temperature laser magnetometer based on optical pumping of cesium atoms that makes it possible to map the magnetic field produced by the beating human heart. A gradiometer formed by two identical sensors greatly reduces the influence of external stray magnetic fields. We have generated spatially resolved movies of the QRS-dynamics of the cardiomagnetic cycle. Our field maps are comparable in quality and in the level of diagnostic information to SQUID-generated maps. | |
