摘要：
An MRI apparatus is characterized in that magnet members for compensating the magnetic field are disposed to a thermal shield system of the superconducting apparatus. It is another feature of the present invention that the magnet members for compensating the magnetic field are disposed at positions where temperature change in the vacuum chamber is not transferred to the interior of the vacuum chamber.
