According to the American Institute of Ultrasound in Medicine, what is the maximum SPTA intensity threshold without bioeffects?

  1. 1 mW/cm2

  2. 1 W/cm2

  3. 100 mW/cm2

  4. 100 W/cm2

The correct answer is: 100 mW/cm2

The maximum SPTA intensity threshold without bioeffects according to the American Institute of Ultrasound in Medicine is 100 mW/cm2. This threshold ensures that ultrasound exposure remains below levels that could potentially cause harmful biological effects. Options A, B, and D exceed this safe threshold and therefore are not correct.
