Abstract:
A method for acquiring an MR image of an object disposed to experience translational motion, said method comprising the steps of:positioning an MR point source in selected spaced-apart relationship with said object;causing said point source to experience substantially the same translational motion as said object;acquiring a set of k-space data representing an image of said object and an image of said point source, collectively;deriving a function representing the square of the magnitude of said k-space data set;applying an inverse Fourier transform operation to said function to generate a number of correlation components, a specified one of said correlation components comprising the cross-correlation of said object and said point source; anddiscarding all of said correlation components except said specified correlation component to provide an image of said object from which effects of said translational motion have been substantially eliminated.
