For development of DNP-MRI in recent years, there is demand of changing the magnetic field during MRI imaging. It is difficult problem that the magnetic field is changed, because traditional MRI require magnetic homogeneity under 100 p.p.m. In the past, several methods were tried. One method used the electromagnet. Another method used the transport between two magnets. However these methods weren’t conclusive. We develop new field cycling MRI rotating two magnets that have 300mT and 13.5mT.
