We report on the use of radio-frequency optical atomic magnetometers formagnetic induction tomography measurements. We demonstrate the imaging of dummytargets of varying conductivities placed in the proximity of the sensor, in anunshielded environment at room-temperature and without background subtraction.The images produced by the system accurately reproduce the characteristics ofthe actual objects. Furthermore, we perform finite element simulations in orderto assess the potential for measuring low-conductivity biological tissues withour system. Our results demonstrate the feasibility of an instrument based onoptical atomic magnetometers for magnetic induction tomography imaging ofbiological samples, in particular for mapping anomalous conductivity in theheart.
