In this report, the left ventricular blood pool of the heart is presented as an image of three dimensions by collecting the data simultaneously with two scintillation cameras from two directions at right angles to one another and processing by a computer system. Our three dimensional procedures, quite different from the conventional two dimensional images, reproduce the cubic structure of the left ventricle. It was confirmed by basic experiments using several phantoms that this three dimensional image reproduced the shape of the object very accurately. The three dimensional images of the left ventricle clearly showed morphological changes and abnormalities in myocardial movement. It is highly valuable in diagnosis because foci of myocardial infarction, akinesis and dyskinesis are clearly detected by this technique. In particular, the fact that the three dimensional images conform well with X-ray cineangiography and 201T1 scanning justifies the value of the clinical application of this technique.
在本报告中，通过使用两台闪烁相机从相互成直角的两个方向同时采集数据，并由计算机系统进行处理，心脏的左心室血池呈现为三维图像。我们的三维成像程序与传统的二维图像截然不同，它再现了左心室的立方结构。使用多个模型进行的基础实验证实，这种三维图像能非常准确地再现物体的形状。左心室的三维图像清晰地显示了心肌运动的形态变化和异常。由于该技术能清晰检测到心肌梗死、运动不能和运动障碍的病灶，因此在诊断中具有很高的价值。特别是，三维图像与X射线电影血管造影和201Tl扫描非常吻合这一事实证明了该技术临床应用的价值。
