When using the submersion method of ultrasound, how far should the transducer face plate be from the treatment area?

In the submersion method of ultrasound treatment, the ideal distance from the transducer face plate to the treatment area is between 0.5 to 1 inch. This distance is critical because it ensures that the ultrasound waves can effectively penetrate the medium for optimal therapeutic effect.

When the transducer is positioned too far from the treatment area, the intensity of the ultrasound waves diminishes as they travel through air or water, leading to less effective treatment. Keeping the transducer within this specified range helps maintain the necessary acoustic energy delivery, allowing the ultrasound to achieve the desired effects such as pain relief or tissue healing.

Maintaining this proximity also helps reduce the risk of air bubbles interfering with the transmission of ultrasound waves, which can occur if the transducer is positioned further away. This is vital for effective tissue engagement during therapy.
