Abstract

Provided are a magnetic resonance imaging apparatus (10), an image processing apparatus, an image processing method, and a program that can suppress the occurrence of striped noise in an image reconstructed based on partial k-space data acquired within an asymmetrical measurement region of the k-space and generate a high-quality image. A magnetic resonance imaging apparatus (10) estimates data of a k-space by applying a half-Fourier method or a POCS method to partial measurement data (PKt) of an asymmetrical measurement region of the k-space, acquires a corrected image (F12B) in which the data of the k-space is reconstructed, acquires a smoothing-corrected image (F12C) obtained by performing smoothing filter processing on the corrected image (F12B), replaces data of the unmeasured region of the smoothing-corrected image (F12C) with zero data, and estimates the data of the unmeasured region using a first trained model.
