A apparatus includes a unit which reconstructs a plurality of pieces of first image data associated with elements or sections, by use of magnetic resonance signals, a unit which determines the coil elements or the sections which have received the magnetic resonance signals which are at least some of the plurality of collected magnetic resonance signals as target elements or target sections, and generates second image data by combining the plurality of pieces of first image data associated with the target elements or the target sections, a display unit which displays an image represented by the second image data, and a unit which changes the target elements or the target sections based on specification after display of the second image, and generates third image data by combining the plurality of pieces of first image data associated with the changed target elements or the changed target sections.
