Which frequency range is most commonly associated with Doppler ultrasound?

Doppler ultrasound is primarily utilized for measuring and assessing blood flow in the body, and it is crucial to choose the right frequency range to obtain accurate and reliable results. Frequencies in the 5-15 MHz range are commonly used in Doppler ultrasound because they strike a balance between providing sufficient resolution to visualize blood vessels and structures while also allowing adequate penetration into tissues to detect flow dynamics.

When the frequency is too low, such as in the 1-5 MHz range, the resolution may not be sufficient for detailed images of the higher frequency movements associated with blood flow. On the other hand, frequencies above 15 MHz may provide exceptional resolution but can lose penetration depth, making them less effective for assessing deeper structures in the body. Thus, the 5-15 MHz range is optimal for Doppler assessments, allowing sonographers to visualize the flow of blood and identify issues such as blockages or abnormalities within vessels effectively.
