Doppler ultrasound is specifically designed to assess blood flow and the movement of tissues. This technique leverages the Doppler effect, which refers to the change in frequency or wavelength of waves in relation to an observer moving relative to the source of the waves. In medical ultrasound, this allows sonographers to evaluate the speed and direction of blood flow within vessels, providing crucial information for diagnosing various conditions such as vascular diseases, heart valve issues, or assessing fetal blood flow during pregnancy.

While other ultrasound techniques like 3D ultrasound, transvaginal ultrasound, and standard ultrasound have their own applications in imaging and examining anatomical structures, they do not specifically facilitate the assessment of blood flow in the way that Doppler ultrasound does. 3D ultrasound is mainly utilized for rendering three-dimensional images for anatomical visualization, transvaginal ultrasound focuses on internal pelvic structures, and standard ultrasound typically provides two-dimensional images of organs and tissues without the capability to measure movement or flow dynamics.
