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

Figure 4

Apodization functions obtained for = 0.8 mm with a regularized WMNLS estimation using different regularization parameter values: (dash-dot line with square, unstable), (solid line with circle, corresponding to the stable apodization function shown in Figure 1(a)), and (dashed line with triangle, the same as that obtained with a Fraunhofer approximation shown in Figure 1(a)).
