Abstract
A storage unit stores coil positional information that indicates a physical position of an element coil relative to a representative position set on a receiving coil. A creating unit creates profile data that indicates a distribution of Nuclear Magnetic Resonance (NMR) signals in a coil-arrangement direction. A calculating unit calculates the position of a representative position set on the receiving coil by performing a regression analysis by using the coil positional information and the profile data. A control unit causes a display unit to display the position of each element coil based on the calculated position of the representative position.
