Magnetic resonance imaging apparatus and magnetic resonance angiography method

摘要

A magnetic resonance imaging apparatus acquires 3D data of a subject, extracts 2D data for ky=constant out of the 3D data concurrently with the collection of 3D data, Fourier-transforms in a z-axis direction the extracted 2D data for ky=constant and rearranges the same on a kx-z space concurrently with the collecting of 3D data, performs a one-dimensional Fourier transform on z-data completed in a kx direction and acquires a 2D image for real space concurrently with the collection of 3D data, and displays a 2D image on a monitor concurrently with the collection of 3D data. Meanwhile, the the 3D data in the z-axis direction is Fourier-transformed and rearranged on a kx-ky-z space, a two-dimensional Fourier transform is performed on the z-data completed in a kx/ky direction and a 3D image is acquired for real space.
