In the context of ultrasound, what is the duty cycle used for?

The duty cycle in ultrasound therapy refers to the ratio of the time the ultrasound is on to the total time of the treatment session. It is a crucial parameter that influences the intensity of treatment. By adjusting the duty cycle, practitioners can modulate the amount of energy delivered to the tissues. A higher duty cycle means a greater proportion of time the ultrasound is applied, which can increase the therapeutic effects, whereas a lower duty cycle may be used to minimize tissue heating and prevent discomfort or injury to the patient.

This concept is essential for tailoring treatments based on the specific therapeutic goals, such as promoting tissue healing or reducing pain. Different conditions may require varying duty cycles to produce the desired physiological effects. Understanding the duty cycle allows healthcare providers to optimize treatment plans and ensure that patients receive the appropriate intensity of ultrasound therapy for their condition.
