Energy absorption and sonic and ultrasonic vibration may reflect the status of internal damage, but both techniques are more suitable for assessing bruise susceptibility.
Ultrasonic scattering and absorption is a complicated processing. Biologic media is composed of water, fat and protein, which is different from even liquid matter.
