Question

Which of the following is necessary to produce a heating effect using ultrasound? a. Using non-thermal parameters b. Non-continuous duty cycle c. Continuous duty cycle d. Ultrasounding a large surface area

Answer 1

Option (a) Using non thermal parameters is correct answer.

Explanation:

Ultrasound technology is a non thermal heating process. Heating of tissues is done through absorption of ultrasound wave when a tissue or object comes in a way of ultrasound wave.

option (b) and (c) says about continuity and discontinuity of producing waves. Depending on application we alter it to continuous or alternate or discontinuity process. So, these options are not correct.

Option (d) says about surface area. If we subject more surface are to ultrasound waves, the effect of heating may reduce. So, ultrasound wave should focus on affected area to get maximum output.

Hence, option (a) is correct.
