“实验数据和几何分析库”或埃德加是一个基于互联网的精选数据档案，免费分发给国际研究界，用于心电图成像（ECGI）技术的应用和验证。埃德加项目是心电图成像联盟（CEI，ecg-imaging.org）的一项合作努力，专注于两个特定目标。一个目标是托管一个在线存储库，提供对广泛数据的访问，第二个目标是为这些不同数据集的交换提供标准信息格式。埃德加系统由两个相互关联的组件组成：1）元数据模型，包括一组描述性参数和信息、来自心脏源和体表的时间信号以及广泛的几何信息，包括图像、几何模型和数据采集/生成期间使用的测量位置;以及2）网络界面。该Web界面提供了对存储库中数据的高效搜索、浏览和检索。通过埃德加项目，可获得来自不同中心的实验、临床和模拟数据的汇总，包括来自犹他州（美国）大学提供的动物研究的实验数据、来自查尔斯大学医院（捷克共和国）提供的多个人类受试者的临床数据以及卡尔斯鲁厄理工学院（德国）提供的计算机模拟数据。我们希望埃德加将成为一个共享和分发用于ECGI研究的心脏电生理数据和几何模型的公共论坛。
The “Experimental Data and Geometric Analysis Repository”, or EDGAR is an Internet-based archive of curated data that are freely distributed to the international research community for the application and validation of electrocardiographic imaging (ECGI) techniques. The EDGAR project is a collaborative effort by the Consortium for ECG Imaging (CEI, ecg-imaging.org), and focused on two specific aims. One aim is to host an online repository that provides access to a wide spectrum of data, and the second aim is to provide a standard information format for the exchange of these diverse datasets. The EDGAR system is comprised of two interrelated components: 1) a metadata model, which includes a set of descriptive parameters and information, time signals from both the cardiac source and body-surface, and extensive geometric information, including images, geometric models, and measure locations used during the data acquisition/generation; and 2) a web interface. This web interface provides efficient, search, browsing, and retrieval of data from the repository. An aggregation of experimental, clinical and simulation data from various centers is being made available through the EDGAR project including experimental data from animal studies provided by the University of Utah (USA), clinical data from multiple human subjects provided by the Charles University Hospital (Czech Republic), and computer simulation data provided by the Karlsruhe Institute of Technology (Germany). It is our hope that EDGAR will serve as a communal forum for sharing and distribution of cardiac electrophysiology data and geometric models for use in ECGI research.
