WebUltrasound imaging devices can use the doppler effect to help us in many ways, including helping us to identify blood vessels.When you scan structures without using the doppler effect, the machine simply sees how long the waves take to return back to the probe and constructs an image. WebUltrasound image is produced when the pulse wave that is generated travels through the body, reflects of the tissue interface (echo0 and returns to the transducer. When the wave is transmitted back to the transducer its amplitude is represented by its brightness or echogenicity. It is represented as a dot.
