Biomagnetometry

Abstract

We have developed a novel, small-volume portable single-channel atomic biomagnetometer and have used it to detect adult MCG signals. The cryogenic-free magnetometer has sufficiently high sensitivity (20 fT/rt(Hz)) that it is fetal MCG capable. It detects two magnetic field components simultaneously and has a bandwidth of typically 50-100 Hz. Extensions to multiple channels will be described.
