Scan time reduction factor achievable when considering the reconstruction obtained with the mCT as the reference. a 440 × 440 and b 220 × 220 matrix size for the Vision (using 3 different numbers of iterations). Right y-axis and dashed lines: contrast improvement for the 10-mm sphere (blue, red, and black lines correspond respectively to 3, 4, and 5 iterations)
