In the following MTF value sequence, which value is the highest?

• A. 0.7
• B. 0.6
• C. 1.0
• D. 0.8

Answer: (C)

MTF values quantify how well an imaging system preserves image contrast at a given spatial frequency. They range from 0 to 1, with 1 representing perfect contrast transfer and 0 representing no transfer. Among the numbers listed, 1.0 is the greatest, indicating the best potential transfer of contrast at that spatial frequency. The other values—0.7, 0.8, and 0.6—are lower, showing progressively less effective contrast transfer. So the highest value is 1.0.
