In A-mode, which axis represents Amplitude?

Explanation:
In A-mode, the height of each spike represents the amplitude of the echo, while the horizontal position tracks the time of flight (and thus depth). So the amplitude is shown on the vertical axis (the Y-axis). Larger spikes indicate stronger reflections from tissue interfaces.
