摘要:
An image reconstruction method according to an embodiment includes: collecting first k-space data at a first time and second k-space data having an undersampled pattern different from an undersampled pattern of the first k-space data at a second time different from the first time; generating intermediate data by converting data including the first k-space data and the second k-space data; generating, by inversely converting the intermediate data, third k-space data and fourth k-space data that correspond to the first k-space data and the second k-space data, respectively, and in each of which at least part of a region undersampled through the corresponding undersampled pattern is filled; and generating a magnetic resonance image at a time different from any of the first time and the second time by converting k-space data obtained by combining at least part of the third k-space data and at least part of the fourth k-space data.
