N1 - Funding Information:
Helium is not produced in Japan, which means that Japan needs to import all helium from foreign countries. Therefore, several research funding agencies affiliated with the Japanese government, such as the Japan Agency for Medical Research and Development (AMED) and New Energy and Industrial Technology Development Organization (NEDO), have been encouraging Japanese universities, research organizations, and industries to throw the development of MRIs capable of using high-temperature SC coils into high gear. Furthermore, the quality of SC coils using REBCO (rare-earth barium copper oxide) has become stable, and a long coil has become available [6].

N2 - Mitsubishi Electric, Tokyo, has been developing a SC-MRI using REBCO coils, together with Kyoto University and Tohoku University, under the supervision by NEDO. The project has been initiated from started 2013, and it aims at the completion of the design of SC magnets for imaging the whole body and putting the developed MRI on the market in 2026. First, Mitsubishi developed a one-third model coil for a three tesla (3 T) MRI. One important development task is to realize a coil structure that would not cause deterioration of the SC characteristics. The second development task is the production of a high-precision coil. The magnetic field at the center of the bore or area where a patient is scanned is 2.9 T, the same as general 3-T MRI systems. The maximum experienced magnetic field has been 4.5 T when the central magnetic field was 3.0 T and the coil passed the current with a density of 113 A/mm 2 .
