6 Range Equation Flashcards
1
Q
What is the “go-return time” or time-of-flight or round trip time?
A
The time needed for a pulse to travel to and from the transducer and the reflector
2
Q
What are directly related to each other since average speed of sound in soft tissue is known?
A
Time-of-flight and distance that sound travels in the body are directly related
3
Q
What is the 13 microsecond rule?
A
In soft tissue, every 13 usec of go-return time means the reflector is 1 cm deeper in the body
4
Q
How is reflector depth and total distance traveled related?
A
Total distance traveled is twice the reflector depth
5
Q
List the equation for speed.
A
Speed = distance/time
