3-D image reconstruction using Fourier transformation with differing resolutions of image axes

摘要

An image reconstruction method of the 3DFT type is proposed wherein the organization of the excitation and measuring sequences comprises the repetition of macro-sequences. During the macro-sequences, a selection encoding gradient which may have a small number of encoding steps (in particular, smaller than the expected resolution of the images) is applied. It is shown that this approach enables the best possible of the power and flexibility of the vectorial processors used to perform image reconstruction computations efficiently. It is shown that the images can then be produced in real time.
