Biplane integration method for left ventricular volume determination is applicable to routine work since digital contour memories, calculation of the cross-section area and summation of all volume slices are computerized. The longest measured axis is recommended for volume calculation. A second calculation with interchanged axis and averaging of both results led to a correlation coefficient (r) of 0.997 (comparison of true volume and calculated volume). Comparison of stroke volume in patients with coronary heart disease determined by the Fick principle and the reported method showed a significantly better correlation for the biplane than for the monoplane method.
双平面积分法测定左心室容积适用于日常工作，因为数字轮廓记忆、横截面积计算以及所有容积切片的求和均已计算机化。建议使用最长测量轴进行容积计算。通过互换轴进行第二次计算并对两个结果求平均值，得出相关系数（r）为0.997（真实容积与计算容积的比较）。用菲克原理和所报道方法测定的冠心病患者每搏输出量的比较表明，双平面法的相关性明显优于单平面法。
