a) Raw sonomicrometer displacement and hemodynamic curves for a given acquisition. Each acquisition generated 462 displacement curves to account for each pair combination of the 22 crystals. b) Video [image] of cycle-dependent crystal positions as determined by 3D crystal coordinate solutions of the displacement curves
