Abstract

An image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry determines, with respect to each of the pixels included in a magnetic resonance image, a shift amount from the position of the pixel to a position where ringing artifacts will be reduced and performs a ringing correction to correct the ringing artifacts occurring in the magnetic resonance image on the basis of the determined shift amounts. The processing circuitry estimates, with respect to each of the pixels, a local amplitude of ringing artifacts, and performs the ringing correction on the magnetic resonance image while determining the shift amount of each of the pixels so as to be approximately continuous with the shift amounts of adjacently positioned pixels, sequentially in descending order starting with pixels having a higher local amplitude on the basis of the estimated local amplitudes of ringing artifacts.
