Images and shear-wave measurements of an anisotropic material. (A) B-mode images of a bovine tendon acquired at direction in parallel and perpendicular to the longitudinal axis of the sample. The image acquired along the longitudinal direction is characterized by parallelly aligned, high echogenicity lines, whereas the perpendicular image is not. The blue box and the yellow circle in both images represent the ROI of shear-wave measurements and the focus of the push transducer, respectively. (B) The shear-wave speeds measured at directions with an inclined angle between the scanned plane and the longitudinal axis of the sample at 0, 45, and 90 degrees, respectively. Data are presented as mean±s.d. and averaged from 5 measurements in each direction.
