Nuclear Magnetic Resonance Radio Frequency System

The nuclear magnetic resonance radio frequency (RF) system comprises RF transmitting system, RF coil and RF signal receiving system. Together, these components form the backbone of the nuclear magnetic resonance (NMR) RF system, enabling accurate imaging and spectroscopy. It emphasizes the importance of RF technology in nuclear magnetic resonance imaging and spectroscopy, which is revolutionary for medical diagnosis, material analysis and scientific exploration. The principle of nuclear magnetic resonance involves the interaction of atomic nuclei with magnetic fields and radio frequency pulses to explore molecules' structure, composition and dynamic processes. This paper discusses the development of NMR RF systems, with emphasis on the design of RF coils, signal modulation strategies, and their interaction with NMR phenomena. Subsequent sections will delve into the complexity of the components of NMR RF systems, explaining RF emissions, RF coils, and RF signal receiving systems. The RF transmitting system generates RF pulses, the RF coil sends and receives signals, and the RF receiving system receives and processes NMR signals.
