MAGNETIC RESONANCE IMAGING DEVICE, AND MAGNETIC RESONANCE ANGIOGRAPHY METHOD

摘要

A magnetic resonance imaging apparatus includes data acquiring means that acquires 3D raw data of a subject, 2D data extract means that extracts 2D data for "ky = 0" out of the 3D raw data concurrently with the acquiring of 3D raw data by the data acquiring means, 2D-data rearranging means that Fourier-transforms in a z-axis direction the extractped 2D data for "ky = 0" and rearranges the same on a kx-z space concurrently with the acquiring of 3D raw data by the data acquiring means, 2D-imade reconstructing means that performs a one-dimensional Fourier transform on z-data completed in a kx direction and acquires a 2D image for a real space concurrently with the acquiring of 3D raw data by the data acquiring means, and a display control means that causes to display a 2D image on a monitor concurrently with the acquiring of 3D raw data by the data acquiring means. Meanwhile, the magnetic resonance imaging apparatus has 3D-data rearranging means that Fourier-transforms the 3D raw data in the z-axis direction and rearranges the same on a kx-ky-z space, and 3D-image reconstructing means that performs a two-dimensional Fourier transform on the z-data completed in a kx/ky direction and acquires a 3D image for a real space, thus calculating a movement rate of the table top according to a rate-change signal inputted on an input device.
