A magnetic resonance imaging device comprises data collecting means for collecting 3D raw data of a specimen, 2D data cutoff means for cutting off, in parallel with the collection of the 3D raw data by the data collecting means, 2D data of "ky = 0" from the 3D raw data, 2D data rearranging means for Fourier-transforming the 2D data of "ky = 0" cut off, in a z-axis direction and rearranging the transformed data in a kx-z space, 2D image reconstructing means for subjecting the z-data arranged in a kx-direction to a one-dimensional Fourier transformation in parallel with the collection of the 3D raw data by the data collecting means, thereby to acquire a 2D image in a real space, and display control means for displaying the 2D image in a monitor in parallel with the 3D raw data collection by the data collecting means. The magnetic resonance imaging device further comprises 3D data rearranging means for Fourier-transforming the 3D raw data in the z-axis direction and rearranging the transformed data in a kx-ky-z space, and 3D image reconstructing means for subjecting the z-data arranged in the kx- and ky-directions to a two-dimensional Fourier transformation thereby to acquire a 3D image in the real space, whereby the moving velocity of a top is calculated according to the velocity change signal inputted at an input device. |
