A Photoacoustic Imaging Algorithm Based on Regularized Smoothed L₀ Norm Minimization

Figure 4

Reconstruction results of the standard General Electric resolution phantom. The first to the third rows are the reconstruction images with 30-view, 40-view, and 50-view that are uniformly distributed at a 360° curve. The first to the fourth columns show the results of TwIST, SPGL1, SL0, and ReSL0 individually.
