The hard and soft reconstructed Young's modulus means and standard deviations computed from the pixels within a given region in one modulus elastogram, reconstructed contrasts, and contrast-to-noise ratios (CNR) for two experiments, the first using only one region and the next using two segmented regions.

	${\stackrel{‒}{E}}_{ves}$	${\stackrel{‒}{E}}_{plq}$	CTE (dB)	CNR
NP	38.2 ± 11.1	34.3 ± 11.2	8.66	0.35
Hard Prior	38.2	14.4	0.81	∞
Soft Prior	38.2 ± 17.3	10.1 ± 4.6	0.92	2.2

The independently measured hard and soft Young's moduli were 38.2 ± 0.8 and 9.5 ± 0.1 kPa. respectively. The actual modulus contrast was approximately 0.75. All modulus values shown were normalized, such that the mean of the harder modulus was equal to the measured value.
