Figure 4:

Cardiac strain values for the computational phantom calculated after combining cDTI and DENSE. (A) Computed Myofiber strain (E_{ff_C}) and (B) circumferential strain (E_{cc_C}) at endo, mid, epi layers, and across the left ventricular (LV) wall. 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 corresponding layer. (C) Transmural distribution of E_{ff_C}, E_{cc_C}, and the absolute difference between E_{ff_C} and E_{cc_C} at peak systole. Blue solid lines represent the transmural median.
