Abstract:
1. A magnetic resonance imaging apparatus comprising: a gantry which has a gradient magnetic coil unit configured for generating a gradiant magnetic field applied to a subject in a magnetostatic field; a bed which allows a top board, on which the subject is placed, to slide in a longitudinal direction; a pulse applying unit which applies a high-frequency pulse to the subject; and a high-frequency coil in which detects a magnetic resonance signal generated from the subject by applying the gradient magnetic fields and the high-frequency pulse, wherein the gradient magnetic coil unit includes a plurality of conducting line members wound in a predetermined winding pattern for each of an x-coil, y-coil, and z-coil, a first resin material filling gaps between the conductor is a of a given coil for each of the plurality of coils, and a different second resin material, which has a higher thermal conduct to the than that of the first resin material, the second resin material filling the interstitial gaps formed between the conducting line members of at least one of the given x, y, z-coils.
