7T whole-body MRI system has received comprehensive praises from the worldwide users, but some patients feel clautrophobic when doing the scanning at the long tunnel. This work proposed a ultra-short design scheme for the 7 T MRI magnet, which is nearly a half of the presented commercial system. In addition, the magnet operates at helium-off enviroment, which saves the precious coolant liquid helium and is also conveinent to maintain.
