Title:
超電導磁石ならびに磁気共鳴撮像装置
Document Type and Number:
Japanese Patent JP6268108
Kind Code:
B2
Abstract:
A superconducting magnet in which efficiency of conduction cooling is improved is described as well as a magnetic resonance imaging apparatus that includes the superconducting magnet and requires no liquid helium. The magnet resonance imaging apparatus includes: a coil portion including a winding core, a winding portion formed by winding a wire around the winding core, a first flange provided on one side of the winding core, and a second flange provided on the other side of the winding core; a cooling device for cooling the coil portion; and a heat conducting member for thermally connecting the coil portion and the cooling device, in which at least one of the first flange, the second flange, and the winding core has a region made of a material whose thermal contraction rate is larger than a thermal contraction rate of the winding portion.
