Figure 3
The blood vessel phantom results reconstruct by different methods. The first to the third rows are the reconstruction results of 10, 20, and 30 views that are evenly distributed on the circumference individually. The first to the fourth columns display results of the Tikhonov , SPGL1, EN , and EN , respectively.
