Here's why:
* Doppler Effect: This is the fundamental principle behind Doppler Ultrasound. It measures the change in frequency of sound waves as they reflect off moving objects (like blood cells in the body). This change in frequency reveals the velocity of the moving object.
* Velocity Mapping: Doppler Ultrasound generates a visual representation of blood flow, showing the direction and speed of blood moving through vessels. This is often displayed in color, with different colors representing different velocities.
* Imaging: Doppler Ultrasound also uses sound waves to create images of internal structures, like blood vessels, organs, and tissues. This is similar to conventional ultrasound imaging.
Therefore, Doppler Ultrasound is the device that combines both velocity mapping and imaging capabilities.
