Figure 1: An illustration of the ultrasonic measurement process of sheep condyle. (a) Anatomic sketch of sheep mandible and condyle. (b) Condyle sample prepared for ultrasonic measurement. (c) Two-dimensional illustration of the bone material cut away so that can be measured. (d) A three-dimensional sketch of the bone sample after all the cuts have been made (shown as hatched parts) as well as the measurement direction for each . 1 was the antero-posterior direction, 2 was the vertical direction, and 3 was the mesio-lateral direction. arrow indicates longitudinal wave speed, which was measured with the generation and sensing transducer in line. carrow indicates the transverse wave speed measured with the generation and sensing transducer at a right angle.
