We propose a new approach to improve the isolation of NMR signals originating from the field probe and from the imaging object without using an independent transceiver. We use an RF coil (Tx loop) to pick up the RF energy during RF transmission to the field probe inside an RF shield. During RF reception, the Tx loop is detuned such that the NMR signal from the imaging object will not be picked up by the Tx loop and the field probe can remain isolated inside the RF shielding. This design is empirically demonstrated by an one-channel prototype system.
