The reconstructed results for straight-line scanning of the Shepp–Logan phantom in the perpendicular direction for TV-GD (a–c), TV-Lp (d–f), Patch-RE (g–i) and patch-TV (j–l). The first, second, and third columns refer to the results for 50- (a, d, g, j), 20- (b, e, h, k), and 10-point (c, f, i, l) sampling, respectively
