Abstract
Typical modern MRI devices are based on first-type superconductors, which need to be cooled by liquid helium. To enhance cost efficiency, the feasibility of utilizing high- temperature superconductors (2nd generation) cooled by liquid nitrogen is currently under investigation. However, it is essential to note that these modern superconductors exhibit a considerably higher noise level, which must be considered when designing the magnet of low- field MRI scanners. Here, we present a method for evaluating the intrinsic noise of high- temperature superconductors for low-field MRI applications.
