摘要: 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.

摘要: A magnetic resonance imaging apparatus includes a sensitivity map data generating unit and a sensitivity corrected image data generating unit. The sensitivity map data generating unit generates reference image data based on data for generating sensitivity map data of a phased array coil and generates the sensitivity map data by using reference image data after correction processing obtained by applying the correction processing to improve a uniformity with the reference image data based on the reference image data and phased array coil data for generating the sensitivity map data. The sensitivity corrected image data generating unit acquires image data for imaging with the phased array coil and performs sensitivity correction of the image data using the sensitivity map data.
