A Thermal Index value of 3 implies what potential tissue temperature change?

Explanation:
Thermal Index represents an estimate of how much tissue heating could occur from ultrasound exposure. A TI of 3 means the tissue at the location being evaluated could experience a temperature rise of about 3°C above normal body temperature, given the current exposure. It’s an upper-bound estimate, not a guaranteed change—the actual rise depends on factors like tissue type, blood flow, depth, and how long the exposure lasts. The value is expressed in Celsius, not Fahrenheit, and it isn’t related to microbubble behavior. So the interpretation is that tissue may rise by up to about 3°C, which matches the option stating a possible rise to 3 degrees Celsius.
