In this paper a parametric model of the left ventricle is presented. Its task is to estimate the myocardium shape on those slices, on which the segmentation algorithm has outlined the structure incorrectly. The aim of using the model on improperly segmented slices is to improve the accuracy of computing cardiac hemodynamic parameters and the heart mass. The proposed model works with any segmentation algorithm. The usefulness of the model is the largest while determining the myocardium at end-systole and calculating the heart mass. In case of the segmentation algorithm applied in this study, the error decreased from clinically unacceptable to acceptable after using the presented model.
本文提出了一种左心室的参数模型。其任务是估计那些分割算法错误地勾勒出结构的切片上的心肌形状。在不正确分割的切片上使用模型的目的是提高计算心脏血液动力学参数和心脏质量的准确性。所提出的模型可以与任何分割算法一起使用。在确定收缩末期的心肌和计算心脏质量时，该模型的用途最大。在应用本文研究中的分割算法的情况下，使用提出的模型后，误差从临床不可接受降低到可接受。
