High quality zoomed MR images.
A zooming technique based on zero filling of the Fourier space is presented for high quality magnification of magnetic resonance magnitude images. Comparison with conventional linear interpolation methods on two clinical examples indicates that Fourier magnification is preferable because it avoids image artifacts and provides superior image quality. It is recommended that this technique become the standard method of magnification on all imagers.
