What does continuous ultrasound imply?

Explanation:
Continuous ultrasound means the energy is delivered without interruption, i.e., a 100% duty cycle. The transducer is on for the entire treatment time, so tissue receives a steady acoustic input, which leads to thermal effects like tissue heating. This is exactly what continuous ultrasound is used for when increasing temperature is desired. By contrast, a duty cycle less than 100% delivers energy in on/off bursts (pulsed), reducing heating and often emphasizing non-thermal effects. So continuous ultrasound implies energy is present throughout and causes heating; it is not zero energy and not anything below 100%.
