 Abstract: We present a miniaturized active nuclear magnetic resonance (NMR) magnetometer consisting of a susceptibility matched field probe and a PCB based RF transceiver. Thanks to its transmit-receive (TX/RX) capabilities, the system can be used to monitor the spatio-temporal field evolution during a magnetic resonance imaging (MRI) scan and thereby allows for a correction of gradient field imperfections to improve image quality. The magnetometer can be tuned for magnetic fields ranging from 7 T to 15.5 T and achieves a resolution of 14.8 nT measured in a 9.4 T whole body scanner.
