Abstract

In this study, we compare the direct and indirect parametric reconstruction approaches (4D and 3D respectively) in terms of their performance in terms of kinetic parameter estimation, and a noise measurement represented by the normalized standard deviation. A numerical phantom with simple geometric shapes has was modelized to evaluate these performances on several sizes of spheres.

摘要

在这项研究中，我们比较了直接参数参数重建方法和间接参数重建方法（分别为4D和3D）在动力学参数估计方面的性能，并以归一化标准差表示了噪声。对具有简单几何形状的数字体模进行了建模，以评估在几种尺寸的球体上的这些性能。
