Journal of Anatomy, EarlyView.Traditional measurement techniques in cadaveric dissection fail to account for the changes in soft tissue length during joint movement. We have developed a new, simple method to obtain more accurate measurements of ligament length and validated using the lateral ankle ligaments group.

Lamb Wave Tomography Using Laser-Based Ultrasonics
, 1995 Lamb waves are widely used for the nondestructive evaluation of plate structures. By using Lamb wave attenuation, velocity and mode conversion, information about the sizes and positions of existing defects can be obtained. Lamb waves have also been used for C-scan imaging of plates.
