摘要

本文提出了一种鲁棒的心脏左心室局部变形分析方法，旨在确定影响区域。我们的方法是基于区域曲率变化的计算，使用Hotelling T2两样本差度量。用44例心肌显像技术的真实数据验证了该方法的有效性。对于每个病人，我们提取三维表面代表感兴趣的解剖结构，即心内膜和心外膜在压力下。为了进一步进行区域分析，我们根据美国心脏协会的标准对每位患者进行了17个区域的划分。实验结果证明了该方法的鲁棒性和有效性。

Analysis of Regional Deformation of the Heart's Left Ventricle Using Curvature Values with Hotelling T2 Metric

This paper presents a robust method of local deformation analysis of the heart's left ventricle (LV) aimed at specifying the affected area. Our method is based on regional curvature variation calculation using the Hotelling T2 two samples difference metric. It has been validated with real data obtained from myocardial scintigraphy imaging techniques of 44 patients. For each patient we extract 3D surfaces representing the anatomical structures of interest, namely the endocardium and epicardium at stress. In order to progress to a regional analysis, we carried out, for each patient, a division into 17 regions according to the AHA standard. Experimental results demonstrate the great robustness and efficiency of our method.
