The GCRG is well-versed in the use of sonomicrometric crystal array localization to obtain extremely high-spatial and temporal resolution in vivo data. Early work using this imaging modality was instrumental in defining borderzone expansion in post-infarction dilated cardiomyopathy (Figure, Jackson et al. , 2002) and mitral annular saddle shape (3rd Gorman et al. , 1996).
Sonomicrometry has since been expanded to understanding complex in vivo mitral leaflet dynamics and tissue properities in collaboration with research partners at Georgia Tech and the University of Texas
