3. In a model of a tissue cross section, a 1 MHz wavefront propagates through uniform layers of either homogeneous connective tissue, muscle, or fat. What are the arrival time differences (measured in ns) and energy level differences (measured in dB) for the following cases? (4 pts) (a) propagation through 5 cm fat, compared to propagation through 5 cm muscle (b) propagation through 5 cm connective tissue, compared to propagation through 5 cm muscle How do your computed arrival time differences compare to the period of the 1 MHz wavefront? Assume straight-ray propagation without any scattering, with tissue properties from the table presented in the lecture notes (Mast, 2000).
