Figure 4From: A photoacoustic image reconstruction method using total variation and nonconvex optimization The FORBILD phantom reconstruction results by different algorithms. The first to the third rows show images reconstructed by the TV-GD (a-d) and TV-Lp algorithm with p = 0.8 (e-h) and p = 0.5 (i-l), respectively. The first to fourth columns refer to the results from 160-view, 90-view, 60-view, 30-view respectively.Back to article page
