Which DEL size is preferred to improve spatial resolution and visualize fine details like fractures?

• A. Small DEL size
• B. Large DEL size
• C. Medium DEL size
• D. Equal DEL size

Answer: (A)

Smaller DEL size yields higher spatial resolution, because the detector samples the image more finely and locates each detected event in a smaller region. This finer sampling reduces blur and lets you distinguish two nearby features that would blur together with larger DELs. Fractures are thin, delicate details, so a small DEL captures their edges more sharply and reveals their true geometry. In practice, this means you can see finer details and separate close features, whereas larger DELs tend to smear them. There are trade-offs like increased noise and longer scan times, but for visualizing fractures, a small DEL size provides the clearest, most detailed image.
