Page 14: Theory Of Measuring Ultrasound Power With The Radiation Force Method
THEORY OF MEASURING ULTRASOUND POWER WITH THE RADIATION FORCE METHOD Sound is a form of energy that sets the particles in the isonated medium into vibrational motion. The particles then possess a kinetic energy. If dP is the rate of the flow of this energy about an area dA, then the mean acoustic energy Eq. - Page 16 9.
