What is the typical frequency range of ultrasound used in vascular imaging?

The typical frequency range of ultrasound used in vascular imaging is between 2 to 10 MHz. This frequency range is optimal for obtaining detailed images of blood vessels and surrounding tissues due to its balance of resolution and penetration. Frequencies lower than 2 MHz can penetrate deeply but lack the resolution needed for visualizing small structures, while frequencies higher than 10 MHz can provide excellent resolution but are limited in their penetration depth, making them less suitable for deeper vascular structures. Therefore, the 2 to 10 MHz range is ideal for evaluating vascular anatomy and hemodynamics in various clinical settings.
