Illustrative Examples for Stepwise Calculation of Plaque Structural Stress From IVUS-VH Through Finite Element Analysis

(A and D) IVUS-VH images showing necrotic core (red), dense calcium (white), fibrofatty tissue (light green), and fibrous (green). (B and E) Reconstructed plaque geometry and segmented plaque components used for finite element analysis. (C and F) Plaque structural stress band plots identifying regions with high stress concentration (arrows indicate areas of high stress at the plaque/lumen boundary). IVUS-VH = intravascular ultrasound-virtual histology.
