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.

这个子项目是许多研究子项目中的一个 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来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 该项目的主要目标是开发一种实用的定量方法，根据超声心动图图像评价局部室壁运动异常，该方法基于具有连续性的非笛卡尔有限元分析，由于其使用广义曲线坐标，特别是长椭球坐标，因此非常适合。有人提出，映射室壁运动的径向长轴坐标，λ，简化了参数表示的endoorthodontic表面，从而提高了检测，量化，和可视化室壁运动异常的能力。
