Applicability of a newly developed volume estimation method was examined with excised left ventricles of pigs and dogs. Serial oblique-sectional images of a left ventricle were recorded with a two-dimensional echocardiograph. The probe of the echocardiograph was fixed at one point and was tilted stepwise. Contours of the left ventricle in the images were traced to put into a computer and volume was calculated. Calculated volume of 19 left ventricles agreed well with true volume in wide range (r = 0.982 for left ventricular myocardium and r = 0.989 for left ventricular cavity).
采用新开发的容积估算方法，对猪和犬的离体左心室进行了适用性研究。用二维超声心动图记录左心室的系列斜切面图像。超声心动图探头固定在一点，并逐步倾斜。描绘图像中左心室的轮廓并输入计算机，然后计算容积。19个左心室的计算容积在很宽的范围内与实际容积高度吻合（左心室心肌的r = 0.982，左心室腔的r = 0.989）。
