Which factor should be adjusted to visualize fine fractures more clearly in digital radiography?

• A. High fill factor
• B. Large DEL pitch
• C. Small DEL size
• D. Low fill factor

Answer: (C)

Spatial resolution in digital radiography comes from how finely the image is sampled by the detector elements. Smaller detector elements mean more samples across the image, so edges and tiny features—like fine fractures—are represented more crisply. If the detector elements are large, the signal is averaged over a bigger area and small cracks blur together with surrounding tissue. Fill factor affects how much of the detector area is active and how strong the signal is, but it doesn’t boost sampling density as effectively as shrinking the detector element size. A large DEL pitch reduces sampling density and also blurs fine details. So the factor that most directly improves visibility of fine fractures is a smaller detector element size.
