Quantitative mapping of lung tissue biomechanics in a live rat. (A) Sample sequential x-ray phase-contrast CT images at successive time points, reconstructed by retrospectively sorting of 250,000 individual image projections with respect to the phase of heart contraction and breathing, b: bronchus, a: artery, h: heart, s: interlobar scissure, r: rib, *: alveoli; (B) sequential local strain maps of vascular structures; (C) sequential regional strain maps of airspaces. Color bars indicate strain (δV/Vt0, where t0 is the start of the breath). Corresponding video animations are provided in the online supplement.
