Performance of the improved elasticity-palpography technique to detect a vulnerable plaque when the whole necrotic core is included in the palpography domain. A) IVUS image of plaque # 2 with plaque constituents (red contours, “nc”: necrotic core; “fi”: fibrous region). The boundaries of the palpography domain Ωpalpo are also given (blue contours). B) Radial strain-elastogram in the palpography domain. C) Computed improved stress-strain modulus (S-SM) palpogram. D) Comparisons between native S-SM of Céspedes et al. (2000), improved S-SM and averaged Young’s modulus (AYM) palpograms.
