Abstract
An image corrected for body motion with high accuracy in a short time when performing retrospective body motion correction on an MRI image is provided, and the time from imaging to image display is reduced. A body motion corrector of an MRI apparatus has a weighting factor calculator that calculates a three-dimensional weighting factor based on signals received by multi-channel receive coils. A processing space converter converts three-dimensional frequency space data of a measurement signal and the three-dimensional weighting factor respectively into hybrid space data and a two-dimensional weighting factor. A synthesized signal calculator calculates a synthesized signal by convolution integration of the hybrid space data and the two-dimensional weighting factor; and a body motion position detector detects a body motion occurrence position in the hybrid space from the hybrid space data and the synthesized signal.
