Figure 10

Modulus profiles obtained from elastograms recovered with the no prior, soft prior and hard prior reconstruction methods over a region of interest defined in figure 1. Showing the profiles obtained from elastograms that were computed from radial displacements with RMS errors of (a) 8% (7.5 dB), (b) 6% (10 dB), and (c) 4% (15 dB). The symbols SP2, SP5, HP2, and HP5 represent the elastograms computed with the SP and HP reconstruction methods, with spatial priors consisting of two and five regions. Similarly, the symbols Truth and NP were used to represent the actual modulus profiles, and the modulus profile obtained with the no-prior inversion scheme.
