| contents | We present a study that evaluates the impact of regularization on the achieved resolution in restorations from a novel three-dimensional (3D) Structured Illumination Microscopy (3D-SIM) system with desirable tunability properties. This contribution is the first performance evaluation of the Tunable SIM (TSIM) system through the restoration process. The study quantifies the achieved resolution in restorations, from simulated TSIM data of a 3D star-like object, at various expected resolution limits controlled by system parameters, and at different noise levels mitigated by the Generalized Wiener filter, a computationally efficient method, successfully applied to other conventional 3D-SIM systems. We show that theoretical TSIM resolution limits are attained in the absence of noise, while with increasing noise levels, the necessary increase in regularization and residual restoration artifacts contributed to a $\sim$ 5%-10% and a 20% reduction in the axial achieved resolution, in 20-dB and 15-dB data, respectively, which is within the pixel size (20 nm) limitation. |
