Figure 5 Four-dimensional tissue synchronization imaging (TSI) of a normal individual. From the different views (left), a three-dimensional impression of the left ventricle is reconstructed (middle). The entire three-dimensional image of the left ventricle is green indicating no dyssynchrony. Post- processing allows the display of the different segments in a polar map format (right) to further facilitate identification of the site of latest activation.
