text: By considering these two parameters, and assuming the depth of the expected image is 150 m m {\displaystyle mm} and the propagation speed of sound at 1500 m / s {\displaystyle m/s} , each line will require 200 μ s {\displaystyle \mu s} to receive the back-scatter information from the farthest focal point.
