RF Coils Virtual Issue
Welcome to the Virtual Issue on RF Coils
Radiofrequency (RF) coils are the “antennae” of NMR and EPR spectrometers, used to both stimulate and receive the NMR or EPR signals acquired to observe the structure or chemistry of materials in physical or living samples. RF coils can take many forms from lumped element solenoids resonant at 10MHz to 100GHz EPR cavities. Coil circuits range from single, passive LC loops to electronically controlled, multiple element phased arrays, to cryogenically cooled probe-heads. Coil applications vary broadly as well, including diagnostic imaging of the human body to spectroscopic determination of empirical formulae of organic molecules. The RF coil is the component of the MRI system by which the MRI signal is stimulated and received or lost. Therefore informed specification, design, construction, evaluation and application of properly selected RF coils are critical to the safe and successful MRI scan.
