Increasing line density has what effect on lateral resolution?

• A. Degrades
• B. Improves
• C. No effect
• D. Deepens imaging depth

Answer: (B)

Line density controls how finely the image is sampled across the width of the beam. When you increase the number of scan lines across the lateral extent, the image samples echoes from nearby locations more closely. This finer sampling lets you distinguish objects that are side by side along the lateral direction, so the image shows clearer separation and detail between adjacent structures. In other words, lateral resolution improves because more lines provide more information about small sideways differences. A practical note: cranking up line density can lower frame rate and raise processing demands, but it does not change how deep the beam can penetrate.
