Two-dimensional calculations for volume calculations using biplane methods of disks (modified Simpson’s method) in apical 4 chamber (A and B) and apical 2 chamber views (C and D). Ejection fraction can be measured from the division of the stroke volume (subtraction of end-systolic volume from end-diastolic volume) by end-diastolic volume.
