Why does continuous wave Doppler not have a highest limit for measuring blood velocity?

Question

Choose only ONE best answer.

A
It has two crystals performing separate functions
B
It only measures blood velocity in small vessels
C
It does not need to send out short bursts of sound waves

Answer 1

A
It has two crystals performing separate functions

Continuous wave Doppler uses two crystals, one for transmitting and one for receiving the sound waves. This allows for continuous transmission and reception of sound waves without needing to send out short bursts.
