Abstract
Provided is a magnetic resonance imaging (MRI) apparatus. The MRI apparatus includes: a storage configured to store a plurality of MR signal data sets generated by applying a plurality of values of a first MR parameter and a plurality of values of a second MR parameter to an MR signal data generation model; a data acquisition unit configured to acquire an MR signal data set for a specific position of an object by undersampling an MR signal, based on the values of the first MR parameter; and an image processor configured to extract an MR signal data set that matches the MR signal data set acquired by undersampling the MR signal (hereinafter referred to as the ‘undersampled MR signal data set’) from among the stored MR signal data sets, obtain a value of the second MR parameter for the undersampled MR signal data set based on the extracted MR signal data set, and interpolate unsampled MR signal data in the undersampled MR signal data set (hereinafter, referred to as the ‘interpolated MR signal data set’) by using the value of the second MR parameter.
