A magnetic resonance imaging apparatus includes an array coil in which a
plurality of element coils are arranged to receive magnetic resonance
signals from a subject, a calculation unit which calculates projection
data for the element coils regarding an arrangement direction of the
plurality of element coils on the basis of the plurality of magnetic
resonance signals received by the plurality of element coils, and a
determination unit which determines the positions of the plurality of
element coils or the position of the array coil on the basis of the
projection data for the plurality of element coils.
