摘要：
The present invention relates to a method for determining right ventricle stroke volume comprising the steps of: providing a plurality of three-dimensional images of right cardiac ventricle of a patient over a cardiac cycle； identically slicing each of the plurality of images； selecting an image from the plurality of images, for each time unit of the cardiac cycle； determining a region of interest in each slice of the selected images, wherein the region of interest shows the right ventricle of the patient； determining area of the region of interest； determining volume of the region of interest； determining total volume of the region of interest for each time unit, wherein the maximum total volume is end diastolic volume and the minimum total volume is end systolic volume； and determining the right ventricle stroke volume using an equation:Right Ventricle Stroke Volume=end diastolic volume−end systolic volume (3).
