Continuous Wave Doppler is a technique of measuring the blood flow and its velocity. It employs two piezoelectric crystals in the same ultrasound transducer; one is applied for sending the continuous signals from the transducer while the other is used for receiving the continuous signal echoes. Both the crystals are mounted at a fixed angle, slightly different for both. This ensures the security from overlapping of the transmitted signal and receiving signal.
As all the signals are continuously transmitted and echoes are received simultaneously therefore it becomes very difficult to differentiate among various signals. This is sometimes a disadvantage in the ultrasound technology. But the improvements are being made further to overcome this problem.
Continuous Wave Doppler is one of the older types of ultrasound technology and imaging technique. The main utility of the CW Doppler technique is its capability to measure accurately high blood velocities which makes it an important part of the core range of medical equipment in clinical facilities.
