From: 3D cone-beam CT with a twin robotic x-ray system in elbow imaging: comparison of image quality to high-resolution multidetector CT

Fig. 4

Boxplots (median and 50% of cases within the boxes) illustrate “undecided” pixel fractions within the intermediate range (25–75%) of signal intensities for cone-beam computed tomography (CBCT) and multidetector computed tomography (MDCT) scans with dose-equivalent scan protocols. Smaller pixel fractions with intermediate signal intensity indicate superior image quality. Except for the difference between regular-dose MDCT and low-dose CBCT, all differences are statistically significant (p < 0.001)
