Figure 1 HeartModel algorithm. The HeartModel algorithm automatically detects three-dimensional end-diastolic and end-systolic endocardial contours of the left ventricle and the left atrium with possibility of further manual adjustments if needed. Right chamber contours are also delineated; however, numerical results are not provided in the current version of the software.
