(a) Schematic layout of the imaging setup with the ultrasound transducer, biceps brachii muscle, muscle fascicle direction, and region of interest (ROI). (b), (c), and (d) The propagation of planar shear waves (white color patches) in the ROI are shown at three different time points: 1ms, 2ms, and 3ms. All three subfigures are zoomed view of the ROI from subfigure (a) with the same orientation at three different time points. The propagation of shear waves towards the elbow on one side and towards shoulder on the other side is visually identifiable.
