Figure 9:
Initial pressure distributions reconstructed by parameterized JR for β = 10−4 with 7 parameters from measured data that (a) ignored mass density variations and (b) included mass density variations. Sound speed distributions reconstructed by parameterized JR with 7 parameters from measured data that (c) ignored mass density variations and (d) included mass density variations. Mass density variations were not included in the reconstruction process. The initial pressure images are shown in a grayscale window of [0.0, 1.1]. The sound speed images are shown in a grayscale window of [1.47, 1.70] mm/μs.
