A method of generating a three-dimensional image of the human left ventricle by computer techniques is described. The volume of each image was estimated by a modification of Simpson's rule. The method was applied to nine suitable patients and estimations of end-diastolic and end-systolic volumes were compared to volumes determined by cineangiography. Significant linear correlation coefficients of 0.95 and 0.94 were obtained for end-diastolic and end-systolic volumes, respectively. The standard errors of estimate were 9 ml for end-diastolic volumes and 7 ml for end-systolic volumes. The value of this methodology lies in the ability to estimate left ventricular volumes with accuracy, using an imaging technique of little inconvenience and no risk to the patient and computer hardware that is readily available at most clinical institutions.
描述了一种通过计算机技术生成人类左心室三维图像的方法。通过对辛普森法则的修改来估计每个图像的体积。该方法应用于九名合适的患者，并将舒张末期和收缩末期容积的估计值与通过电影血管造影术确定的容积进行比较。舒张末期和收缩末期容积分别获得了0.95和0.94的显著线性相关系数。舒张末期容积的估计标准误差为9毫升，收缩末期容积的估计标准误差为7毫升。这种方法的价值在于能够准确估计左心室容积，使用的成像技术对患者不便之处少且无风险，并且大多数临床机构都易于获得计算机硬件。
