Numerical Evaluation of Image Contrast for Thicker and Thinner Objects among Current Intraoral Digital Imaging Systems
Comparison of Gray Values for Thicker Aluminum Step Wedges. D, V, and M indicate the Digora, VistaScan, and Megadixel detectors’ values. Bold lines of the detectors (D3.2, V3.2, and M1.6) show the Gray levels at standard exposure. (a) Exposure condition with only the aluminum step wedge. (b) Exposure condition with the aluminum step wedge and the lead plate.
