Abstract: A gradient coil according to an embodiment is configured to generate gradient magnetic fields along a plurality of axes in an imaging space in which a subject is imaged. The gradient coil includes a coil corresponding to at least one of the plurality of axes, wherein an electrically-conductive member of the coil is formed so as to be partitioned in a thickness direction by a plurality of electrically-insulative layers.

Abstract: A magnetic resonance imaging apparatus according to an embodiment includes a processor. The processor acquires age information representing the length of time elapsed from the birth of a subject. The processor also outputs a parameter of a pulse sequence for imaging an image of the subject, in a manner suitable for the magnetization relaxation characteristic of the subject, the magnetization relaxation characteristic being based on the acquired age information and relaxation characteristic information. The relaxation characteristic information includes mapping of the age information and the magnetization relaxation characteristic.
