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.

该子项目是利用该技术的众多研究子项目之一 资源由 NIH/NCRR 资助的中心拨款提供。子项目及 研究者 (PI) 可能已从 NIH 的另一个来源获得主要资金， 因此可以在其他 CRISP 条目中表示。列出的机构是 对于中心来说，它不一定是研究者的机构。 该项目的主要目标是开发一种实用的定量方法来评估局部心室壁运动 基于具有连续性的非笛卡尔有限元分析的超声心动图图像的异常，这是 由于其公式使用广义曲线坐标，尤其是长椭球坐标，因此非常适合。这是 提出根据径向长长坐标 lamda 映射壁运动，简化了参数化 心内膜表面的表示，从而增强检测、量化和可视化室壁运动的能力 异常。
