Multiple Choice

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

Explanation:
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.
