Ratio measurements for determining the amount of backscattering for muscle, (a) F/B and (b) T/B. These ratios are outlined in Experimental Methods. The average ratios are F/B=478±39 and T/B=4.9±1. With these ratios, we determine that the probability of backscattering for muscle is Pbs = 0.8 ± 0.3%. (c) Backward image of a thin section (∼10 μm) of skeletal muscle (x = 18 μm and y = 18 μm). (d) Thick ex vivo image of an intact muscle tissue block (same dimension as in c).
