ABSTRACT:
An NMR imaging system performs a scan to acquire three sets of data which are Fourier transformed to produce three image data arrays. A corrected image data array is calculated from corresponding elements in the three acquired image data arrays. Image artifacts which cause ghosts in the reconstructed image are masked from the corrected image data by the calculations.
