Numerous advancements have contributed to the success of the technique, including hyperpolarized contrast agents that enables real-time imaging of metabolism in vivo. In physics, hyperpolarization has enabled an NMR RASER using a custom low-field setup and high-Q coils only recently. Expanding on this discovery, we report the finding of a RASER emitting 1H NMR signal continuously for more than 10 min at a high frequency of 600 MHz.
