Abstract
A comprehensive and integrated solution, including a dedicated system structure and grounding mechanism, a main radio frequency (RF) coil to transmit and receive signal, secondary RF coils to saturate unwanted signals from non-region-of-interest (ROI) in the excited region, an RF shielding structure configured to shield the main RF coil from generating signals on the non-ROI, and an environmental noise active cancellation mechanism is proposed to construct an NMR system for non-invasive quantitative detection of organs, and further improves the target region selectivity and detection accuracy.
