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

Explanation:
In A-mode, you’re looking at a one-dimensional depth profile: echoes are shown as spikes along a horizontal axis that represents how far away a reflector is from the transducer. The time between emission and reception (time of flight) is converted into distance using the known speed of sound in tissue, so the axis becomes reflector depth. The height of each spike shows the echo’s amplitude (strength). So the x-axis corresponds to reflector depth, not time or amplitude.
