Continuous wave doppler, Biology

Assignment Help:

In continuous wave Doppler, the transducer has two Doppler crystals, one to constantly transmit and one to continuously receive.

As a result of this continuous mode of transmitting and receiving, motion of blood and tissue occurring all along the ultrasound beam will be  received, analysed and displayed without an  indication of the depth from which each velocity arose. Also, the maximal frequency shift that can be  recorded by continuous wave Doppler  is not  limited by  the PRF or the Nyquist phenomenon hence, it is used to detect and record  the highest velocity available.
