本文提出了一种从单平面（A-P）投影片计算左心室容积的方法。该方法基于LV腔可以由旋转椭圆体（长球体）参考图形表示的假设。根据在A-P和左侧胸部投影中拍摄的双平面X线片测量值计算LV容积。双平面研究表明，前后径与室壁侧径密切相关。仅在A-P膜上进行的测量计算出的体积与双平面计算的体积非常接近。使用单平面技术不会导致绝对收缩末期容积或每搏输出量的计算出现显著误差。
A method Is presented for calculating LW [left ventricular volume] from films taken in a single (A-P [anteroposterior]) plane projection. This method is based on the assumption that the LV chamber can be represented by an ellipsoid of revolution (prolate spheroid) reference figure. LV volumes were calculated from measurements made on biplane films taken in the A-P and left lateral chest projections. The biplane studies demonstrated that the A-P and lateral diameters of the ventricular chamber were closely related. Volumes calculated from measurements made only on A-P films closely agreed with biplane calculations of volume. The use of single plane techniques did not result in significant errors for the calculation of absolute end-systolic volume or stroke volume.
