The phase shift effect is similar to the Doppler shift observed with sound waves. With the Doppler shift, the sound pitch of an object moving toward your location is higher due to compression of sound waves. As an object moves away from your location, sound waves are stretched resulting in a lower frequency.
The three basic types of Doppler ultrasound are: Bedside or continuous wave Doppler. This type uses the change in pitch of the sound waves to provide information about blood flow through a blood vessel. The doctor listens to the sounds made by the transducer to assess the blood flow through an area that may be blocked or narrowed. This type of ultrasound can be done at the bedside in the hospital. It uses a portable machine that can quickly check the extent of blood vessel damage or disease.
