Figure 3:

Cardiac strains measured in the computational phantom using synthetic DENSE images. (A) Measured circumferential (E_{cc_M}) and radial strain (E_{rr_M}) are calculated from DENSE using 2D displacement encoding in a short-axis view at base, mid, and apical levels. (B) Measured longitudinal strain (E_{ll_M}) was calculated from DENSE using 2D displacement encoding in long axis 2-, 4-, and 3- chamber views. The red dashed line provides a −0.15 strain reference; the colored dashed and dotted lines represent the median strain and the first and third quartiles across the slice. The black dashed and dotted lines represent the median ground truth strain and the first and third quartile across the slice.
