1. A method comprising: obtaining multiple coil images of an imaged object; reconstructing a first reconstructed image based on the multiple coil images according to a first reconstruction algorithm; reconstructing a second reconstructed image based on the multiple coil images according to a second reconstruction algorithm; generating correction information about the first reconstructed image based on the first reconstructed image and the second reconstructed image; and generating a third reconstructed image based on the first reconstructed image and the correction information about the first reconstructed image.
