Abstract:
A method of scanning an object in a FOV by acquiring an MRI signal from the object at different projections of a spatially encoding magnetic field, using a plurality of receiving antennas, and reconstructing an MRI image of the object, comprising:
a) at each projection, acquiring the MRI signal from the receiving antennas;
b) filtering the received signal, for at least some of the projections, by applying different time windows to different components of the signal in different frequency bands, and/or received by different receiver antennas, resulting in a filtered received signal vector whose components describe the filtered received signal as a function of time, at each projection, for one or more receiver antennas; and
c) reconstructing an image as a vector whose components describe a weighted or unweighted net magnetization at each voxel in the FOV, that would be expected to produce the filtered received signal vector.
