Figure 7From: A photoacoustic image reconstruction method using total variation and nonconvex optimization The reconstruction results from noisy signal. The first to the third columns 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, from signals with SNR of 10 dB, 5 dB, 3 dB and 0 dB.Back to article page
