A Comparative Study of Four Total Variational Regularization Reconstruction Algorithms for Sparse-View Photoacoustic Imaging

<div>Reconstruction results of the blood vessel phantom. The first to the third rows are the reconstruction images with 20-view, 30-view, and 40-view that are uniformly distributed at a 360° curve. The first to the fourth columns show the results of TVAL3, L1magic, NESTA, and TwIST individually.</div>
