Reflectivity


 * Reference for term: Musculoskeletal ultrasound: Musculoskeletal ultrasound - Holsbeeck Van, M. et al.
 * Technical definition: Combination of factors that determine the intensity of a reflected echo from an interface.
 * Reference for definition: U. physics: Ultrasound Physics and Instrumentation - Hedrick, W. et al.
 * Comment: Two factors influence reflectivity: the acoustic impedance of the two materials and the angle of incidence of the sound beam. Reflectivity is greatest at interfaces between materials with dissimilar acoustic impedance.
