def shift_ifft(fh):
    nx = fh.shape[0]
    ny = fh.shape[1]
    p0 = nx / 2
    q0 = ny / 2

    X, Y = np.meshgrid(np.arange(-p0, -p0 + nx) % nx,
                       np.arange(-q0, -q0 + ny) % ny,
                       indexing='ij')
    fs = T2FFT.synthesize(fh, axes=(0, 1))

    f = fs[X, Y, ...]

    return f
