Medical device
Sonomicrometry was originally applied in the study of cardiac function in research animals by Dean Franklin in 1956, and was quickly adopted by biologists working in biomechanics as well as other physiological organ systems and structures (gastro-intestinal, uro-genital and musculo-skeletal). Medical device companies also use sonomicrometry to assess the physical performance, durability and longevity of devices during R&amp;D phase of development. Sonomicrometry is currently the most prevalent method for determining muscle length changes during animal locomotion, feeding, and other biomechanical functions.
