The authors designed and constructed device simulating the activity of the heart, based on periodic filling and emptying two rubber blowers a radioactive solution by means of two pistons in cylinders operated by two specially shaped cams. The phantom enables to control the correctness of the method and a computer programme for evaluating parameters of heart activity (ejection fraction, end-diastolic volume, pulse volume etc.) in balanced ventriculography performed by a scintillation camera coupled with a computer. The performed measurements have shown a very good agreement of the evaluated parameters with those set at the phantom. The designed device is of an original construction and was granted the author's certificate No. 238,298.
作者设计并制造了一种模拟心脏活动的装置，该装置通过两个特殊形状的凸轮操作气缸中的两个活塞，周期性地填充和排空两个橡胶风箱中的放射性溶液。该模型能够控制方法的正确性，以及用于评估通过与计算机相连的闪烁相机进行的平衡心室造影中心脏活动参数（射血分数、舒张末期容积、脉冲容积等）的计算机程序。所进行的测量表明，评估参数与模型设定的参数非常吻合。所设计的装置结构新颖，并获得了第238298号作者证书。
