What does the term "watts" refer to in the context of ultrasound therapy?

In the context of ultrasound therapy, the term "watts" refers to the power produced by the ultrasound unit at the sound head. Power is a crucial aspect of ultrasound therapy as it determines the strength of the sound waves emitted into the tissues. Higher power settings can lead to deeper penetration and potentially more effective treatment for conditions such as inflammation or tissue repair.

While frequency, duration, and intensity are significant aspects of ultrasound therapy, they do not directly correspond to the measurement of watts. Frequency relates to how often the waves oscillate, duration pertains to how long the treatment is applied, and intensity typically refers to the distribution of energy per unit area, often expressed in watts per centimeter squared (W/cm²). Understanding the role of watts in ultrasound machinery is vital for proper administration and effectiveness of the therapy.
