The suitability of a 3-dimensional filter in diminishing the statistical noise of left ventricular volume curves without any systematical error in the left ventricular ejection fraction (EF) was investigated. The EF values were compared in 50 studies on 24 patients. There was no significant systematical difference between the EFs before and after filtering. The filter diminishes the statistical uncertainty of the EF by a factor of 0.47. Therefore, the method may possibly be employed in processing the left ventricular volume curves.
研究了一种三维滤波器在减少左心室容积曲线统计噪声且不产生左心室射血分数（EF）系统误差方面的适用性。在对24例患者的50项研究中比较了EF值。滤波前后的EF值之间无显著系统差异。该滤波器将EF的统计不确定性降低了0.47倍。因此，该方法可能可用于处理左心室容积曲线。
