After acquisition of a digital equilibrium gamma-angiocardiographie, circumferential analysis of end-diastolic and end-systolic frames gives 120 points diastolic and systolic curves. Their difference represents systolic volume and leads to regional left ventricular ejection fraction assessment at the considered radius level. The circumferential analysis evolute gives the regional left ventricular ejection fraction representative curves which allows especially differential diagnosis between left ventricular akinesia and dyskinesia.
在获取数字平衡伽马血管造影后，对舒张末期和收缩末期图像进行圆周分析可得到120个舒张期和收缩期曲线点。它们的差值代表收缩期容积，并可在特定半径水平评估局部左心室射血分数。圆周分析演变曲线可得到局部左心室射血分数代表性曲线，尤其有助于鉴别左心室运动减弱和运动障碍。
