What is the maximum depth of tissue heating using ultrasound at a frequency of 1 MHz?

• A. One centimeter
• B. Two centimeters
• C. Five centimeters
• D. Ten centimeters

Answer: (C)

The maximum depth of tissue heating using ultrasound at a frequency of 1 MHz is indeed around five centimeters. Ultrasonic therapy relies on sound waves to penetrate tissues, and the frequency used plays a significant role in determining how deep these waves can effectively reach and heat the tissues. At 1 MHz, ultrasound waves can effectively penetrate deeper into the tissue compared to higher frequencies, such as 3 MHz, which primarily heats superficial tissues. The 1 MHz frequency allows for a more profound therapeutic effect as the waves are capable of traveling further into the body, typically achieving effective heating at depths up to about five centimeters. This depth is especially beneficial for conditions that require deeper tissue therapy, such as in the case of deeper muscle strains or joint issues. Understanding the depth of penetration is critical for practitioners to apply ultrasound therapy effectively and safely, ensuring optimal therapeutic outcomes.
