Figure 14From: A photoacoustic image reconstruction method using total variation and nonconvex optimization The amplitudes histograms of the difference between reconstruction results and the “standard” one. We use the image reconstructed by L1-norm with data from all 180 transducer elements as the standard. (a) Histograms image of the FBP algorithm. (b) Histograms image of the TV-GD algorithm. (c) Histograms image of the TV-Lp algorithm.Back to article page
