Summary of the measurements from Figs. 2 and 3

Description	F/B	LE/B	T/B	Pbs % (lipid emulsion)	Pbs % (intact thick ex vivo tissue)
Achilles tendon	24.9 (2.4)	10.6 (1.4)	6.2 (0.8)	39 (10)	21 (6)
Fascia	4.2 (0.1)	2.7 (0.2)	1.1 (0.4)	41 (7)	2 (11)

The measurement errors are in brackets (±). F, signal in the forward direction. B, signal in the backward direction from a thin sample (thickness ∼10 μm). LE: signal in the backward direction for a thin sample with 20% intralipid emulsion added on top. T, signal in the backward direction from intact tissue block (thickness of ∼5 mm). P_bs, fraction of forward signal contributing to the overall backward signal due to backscattering. The ratios F/B, LE/B, and T/B are outlined in Experimental Methods.
