Respuesta :
The medical equipment used for ultrasound imaging is based on Doppler's effect.
The ultrasound imaging process uses high frequency radio waves to view inside images like tendons,muscles,joints,blood vessels etc.
In this process the transmitted pulse produces a Doppler's shift when it interacts with the moving reflector. Here we have to consider the moving reflector as the moving source.The moving reflector will produce an echo which will be received by the transducer.The transducer acts as stationary observer.
The whole process can be explained as below-
1-The ultrasound machine transmits the high frequency signal to the body through a prove.The sound will be reflected by the boundary of tissue and received by the probe.Some sound waves penetrate more into inside part of the body.
2-The received reflected sound will be allowed to enter into the machine which calculates the distance between various tissue and forms an image based on Doppler's shift.
Hence the correct answer is Doppler's effect.
Answer:
the Doppler effect
Explanation:
The frequency of the sound waves used in Doppler ultrasound are high frequency sound waves. These are used to observe and measure the amount of blood that is flowing through the arteries and veins . The veins that supply the blood to arms and legs are studied using the Doppler ultrasound technology.
The ultrasound waves can accurately measure the movement of the red blood cells, since their movement can produce a change in the frequency of the sound waves that are reflected.
