Abstract: Provided is an image in which noise and artifacts, which pose a problem in intraoperative MRI, are reduced and a decrease in sharpness due to noise reduction for a tissue or a site, for which high visibility is required, is suppressed. In a case of generating and presenting a third MR image by using a first MR image acquired by an MRI apparatus and a second MR image obtained by performing processing of reducing noise and artifacts with respect to the first MR image, a difference for each pixel between the first MR image and the second MR image is taken, and a weighting value for each pixel is calculated using a generated difference image. The weighting value is used to combine the first MR image and the second MR image through weighted averaging for each pixel, and the combined image is presented.
