Between 0.5 mm and 0.1 mm DELs, which provides higher spatial resolution?

Between 0.5 mm and 0.1 mm DELs, which provides higher spatial resolution?

• A. 0.5 mm
• B. 0.1 mm
• C. Both provide equal resolution
• D. Neither affects resolution

Answer: (B)

Spatial resolution depends on how finely the image is sampled by the detector. Smaller detector elements sample the image more densely, letting you distinguish finer details. So a detector element length of 0.1 mm captures details about 0.1 mm apart, giving higher spatial resolution than a 0.5 mm element, which would blur features smaller than about 0.5 mm. The option with the smaller DEL is the better choice because it directly improves the ability to resolve small features. Larger DELs reduce resolution, and saying the two are equal or that DELs don’t affect resolution misses this direct relationship.
