PARAMETERIZATION OF CARDIAC WALL MOTION: REUNITING ENGINEERING & CARDIOLOGY

这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 该项目的主要目标是开发一种实用的定量方法，从超声心动图图像中评估局部室壁运动异常，该方法基于具有连续性的非笛卡尔有限元分析，由于其公式使用广义曲线坐标，特别是长球面坐标，因此非常适合。提出了用径向延长坐标Lamda映射室壁运动，简化了心内膜表面的参数表示，从而增强了检测、量化和可视化室壁运动异常的能力。

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.
