    摘要: Systems and methods can quantify cardiac function. In one embodiment, a method (10) for quantifying cardiac function for a patient's heart includes determining (12) an end-systolic strain for each of a plurality of myocardial segments at end systole and determining (14) a peak strain in each of the plurality of myocardial segments. A difference between the peak strain and the end-systolic strain is computed (16) for each of the plurality of myocardial segments. A strain delay index is computed (18) from the computed differences.
