In vitro estimation of fast and slow wave parameters of thin trabecular bone using space-alternating generalized expectation–maximization algorithm

► The wave propagation in thin trabecular bone is performed using Biot’s FDTD method. ► The Biot’s fast and slow waves are superimposed. ► The SAGE algorithm was used as a new approach for slow and fast waves separation. In testing cancellous bone using ultrasound, two types of longitudinal Biot’s w...
