A magnetic resonance imaging (MRI) apparatus comprising:
- a static coil unit configured to form a static field in a subject;
- a gradient coil unit configured to form a gradient field in the static field, wherein the gradient coil unit includes one or more shims arranged in an outermost part of the gradient coil unit to provide homogeneity of the static field formed by the static coil unit;
- and
- a cooler formed inside the shims, wherein the cooler is configured to prevent a temperature of the shims from being raised at least beyond a threshold temperature by heat transferred to the shims.
