Why these controls?
Depth sets the question you ask the device — how deep is the target? Sound speed sets the tissue property the device must assume. Move them to see how the round-trip time grows with distance and why tissue type changes the answer.

1.2987e-4 seconds
- One-way depth
- 10.0 cm
- Travel distance
- 0.200 m
Formula
t = 2d / c
- t = round-trip time in seconds (s)
- d = one-way target depth in meters (m)
- c = speed of sound in meters per second (m/s)
Assumptions
- The pulse travels straight to the reflector and returns along the same path.
- Sound speed is constant and uniform throughout the selected tissue path.
- Processing delay, refraction, attenuation and transducer response time are neglected.
- The entered depth is one-way, so the total travel distance is twice the depth.
