Which energy form is produced when acoustic energy is absorbed by tissue?

• A. Heat
• B. Microbubbles
• C. Kinetic energy
• D. Decibels

Answer: (A)

When acoustic energy enters tissue, part of it is absorbed rather than transmitted or scattered. The absorbed energy is converted into thermal energy, causing a small increase in temperature in the tissue. This heating is the energy form produced by absorption. In diagnostic ultrasound, this heating is usually very small and kept within safety limits. Microbubbles relate to cavitation or contrast agents, not a direct product of absorption in tissue, and decibels are a unit for measuring sound intensity, not an energy form generated by tissue absorption.
