What is a doppler carotid artery?
Doppler carotid artery is a special type of ultrasonic device that relies on Doppler effect to determine the amount of blood flow through carotid arteries. Carotid arteries are two arteries that are located in front of the neck that are responsible for transporting oxygenated blood from the heart to the neck and brain. Generally, the arteries doppler are used in these arteries to detect stenosis or narrowing. It can also be used to check potential blockades, detects the artery wall and verification of stent location, which is a device used to maintain blood flow.
Ultrasonic machine, such as Doppler Carotid Terery, uses sonography to obtain an image of carotid arteries. Sonography refers to the process of exposing the body to sound waves at very high frequencies and using reflections of these waves creates pictures of body organs. In general, the sound waves are emitted by a hand wand that is located straight on the skin. Waves penetrate into the skin and after affecting the organ or other internal structure withDear back. Then the device inside the ultrasonic machine known as the converter determines the distance of the object and whether it contains liquid, air or is solid and constructs an image of the image that is then visible on the monitor.
To evaluate how the blood flows through carotid arteries, the Doppler of the carotid artery relies on what is called the Doppler effect. Doppler's effect, which is named for the Austrian physicist Christian Doppler, refers to a change in wavelength and frequency of sound waves and other types of waves for observers, which is due to the place that the wave originated. In general, when the waves move towards the observer, the distance between the waves shortens. The opposite occurs when the waves move away from the observer.
How much the frequency and wavelength of sound waves change depends on how quickly the object moves. Measurement of wavelength and frequency change can determine how speedle the object moves. This evaluates the doppler of the carotid artery. It uses a change in wavelength to determine how fast blood flows through the arteries. Knowledge of blood flow rate then allows the user to determine whether blood flows through the arteries at normal levels.
