A higher dynamic range setting in ultrasound imaging primarily results in which change to the displayed image?

• A. Image contrast/gray-scale display
• B. Temporal resolution
• C. Penetration
• D. Lateral resolution

Answer: (A)

Dynamic range in ultrasound is about how many gray shades the display can show for echoed signals. A higher dynamic range adds more gray levels, so subtle differences in tissue echogenicity become visible and the image looks smoother with more nuance in shading. This mainly alters the gray-scale display and overall image contrast, while leaving frame rate (temporal resolution), depth of penetration, or beam sharpness (lateral resolution) governed by other factors.
