The application of an edge detection algorithm (EDA) in defining the boundary of the left ventricle (LV) in multiple gated (MG) cardiac studies has been assessed by comparison of the left ventricular ejection fraction (LVEF) derived from X-ray contrast ventriculography (CV) in a series of patients. The results demonstrate good correlation between methods irrespective of the projection and LV status when an EDA is used, such that the correlation in anterior and left anterior oblique (45 degrees) views is 0.91 and 0.86 respectively.
通过比较一系列患者经X射线造影心室造影（CV）得出的左心室射血分数（LVEF），评估了边缘检测算法（EDA）在多门控（MG）心脏研究中定义左心室（LV）边界的应用。结果表明，无论采用何种投影方式以及LV状态如何，当使用EDA时，两种方法之间均具有良好的相关性，在前视图和左前斜位（45度）视图中的相关性分别为0.91和0.86。
