The use of the Doppler effect in ultrasound to detect red blood cells.
An ultrasound scanning technique that produces images of structures inside the body and can provide information about blood flow rate at the same time. Doppler ultrasound creates an image of the area being scanned by processing the echoes produced by harmless, high-frequency sound waves as they strike moving material, such as blood moving through the blood vessels. This information indicates flow through a blood vessel by interpreting the changes in the frequency of the sound.
The utilization of an ultrasound technique known as “continuous wave” offers a means of assessing frequency shifts. In this method, valuable diagnostic data is represented and conveyed through the alteration of frequencies within the echoes that are received.
Within the field of medical diagnostics, there exists a valuable procedure that harnesses the power of sound waves to assess and evaluate the flow of blood through major arteries and veins. This diagnostic technique provides healthcare professionals with crucial insights into the circulatory system, enabling them to gather vital information about blood flow and detect potential abnormalities or conditions related to vascular health.
