该子项目是利用 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得主要资金， 因此可以在其他CRISP条目中表示。所列机构为 中心，不一定是研究者的机构。 本课题的主要目的是建立一种实用的定量评价局部室壁运动的方法 超声心动图图像的异常基于非笛卡尔有限元分析的连续性， 由于其公式使用广义曲线坐标，特别是长球体坐标，因此非常适合。是 提出根据径向长轴坐标λ来映射壁运动，简化了参数化 并且因此增强了检测、量化和可视化壁运动的能力 异常

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The major goal of this project is to develop a practical, quantitative method of evaluating regional ventricular wall motion abnormalities from echocardiographic images based on a non-Cartesian finite element analysis with Continuity, which is ideally suited due to its formulation using generalized curvilinear coordinates, especially prolate spheroidal coordinates. It is proposed that mapping wall motion in terms of the radial prolate coordinate, lamda, simplifies the parametric representation of the endocardial surface and thus enhances the ability to detect, quantify, and visualize wall motion abnormalities.
