With B-mode weaker reflections appear as _____ dots whereas stringer reflections appear as ______ dots.

• A. Darker grey; Brighter white
• B. Brighter white; Darker grey
• C. Darker grey; Darker grey
• D. Brighter white; Brighter white

Answer: (A)

In B-mode imaging, brightness encodes how strong the returning echo is. A weaker echo has a smaller amplitude, so it prints as a darker gray dot. A strong, high-amplitude echo—like a stringer reflection—produces a bright, white dot on the display. So weaker reflections appear as darker gray dots, while stringer reflections appear as brighter white dots because brightness directly reflects echo strength.
