Determination of Lateral Modulation Apodization Functions Using a Regularized, Weighted Least Squares Estimation

Figure 1

Apodization functions obtained using a regularized WMNLS estimation (solid line with circles), a Fraunhofer approximation (dashed line with triangles), and a SVD (dash-dot line with squares) for designed lateral Gaussian-type PSFs with (a) = 0.8 and (b) 0.6 mm. The widths of two peaks at the normalized apodization value 0.3 are also shown.
