What is the best way to adjust ultrasound frequency for deep tissue treatment?

The best way to adjust ultrasound frequency for deep tissue treatment is to decrease the frequency for better penetration. Lower frequencies (typically around 1 MHz) are utilized for deeper tissues because they facilitate greater tissue penetration. Higher frequencies (such as 3 MHz) are more effective for superficial tissues as they have a shorter wavelength, which limits their depth of penetration.

When targeting deeper structures such as muscles or joints located several centimeters beneath the skin, choosing a lower frequency allows for more effective transfer of ultrasound energy into those tissues, resulting in a therapeutic effect. In contrast, if a higher frequency were used, it would not be able to effectively reach the intended deeper tissues, diminishing the treatment's efficacy.

It's important to choose the frequency based on the anatomical depth of the tissues to ensure optimal treatment outcomes. Focusing on intensity instead of frequency does not address the fundamental issue of penetration depth necessary for effective ultrasound therapy in deep tissues.
