A dynamic cardiac phantom was used to provide identical input data at 11 different nuclear medicine laboratories throughout the Philadelphia area, and the variability in the resulting calculations of ejection fraction (EF) was assessed. The variability observed between different operators using the same computer system averaged 3 EF units, which was similar to that between different observers using different types of computers. In the range of low ejection fractions, however, there was a suggestion that EFs calculated with an MDS computer were slightly lower than those from a DEC computer.
使用一个动态心脏模型在费城地区的11个不同核医学实验室提供相同的输入数据，并评估所得射血分数（EF）计算结果的可变性。使用同一计算机系统的不同操作人员之间观察到的可变性平均为3个EF单位，这与使用不同类型计算机的不同观察者之间的可变性相似。然而，在低射血分数范围内，有迹象表明，使用MDS计算机计算的EF略低于使用DEC计算机计算的EF。
