Result of cine-CBCT image (one breathe cycle) reconstruction from a full-fan scan with T = 720. (a) Restored cine-CBCT image with the relative error 7.42%. From left to right: frame 100, 240, 380, 520, 660. Display window is (−1000,420) HU. (b) Absolute value of the differences to the ground truth. Display window is (0,1420) HU. (c) Columns of L. Each column is reshaped into an image. (d) Rows of R.
