摘要: A magnetic resonance imaging (MRI) apparatus and method are provided. The MRI apparatus includes a first interpolator configured to generate a plurality of first interpolation data by performing calibration on a plurality of undersampled K-space data obtained from a plurality of channel coils in a radio frequency (RF) multi-coil, respectively, and a second interpolator configured to generate a plurality of second interpolation data by performing calibration on a plurality of filtered data obtained by filtering the first interpolation data using a plurality of high-pass filters.
