In A-mode, the y-axis represents which quantity?

Explanation:
In A-mode ultrasound, the display is a single line where depth is laid out along the horizontal axis (based on the time it takes for the pulse to travel to a boundary and back). The vertical axis shows how strong the echo is from each boundary—the amplitude of the reflection. So the height of each spike on the vertical axis represents the reflection amplitude, not the depth or time of flight. Brightness is a notion you see in B-mode displays, not A-mode.
