Model Reproducibility Study on Left Atrial Fibres

This dataset contains 100 models of the left atrium. Models come from 50 distinct patients, divided amongst 5 users to assess for inter- and intra-operator variability. The split used was 30 pairs (60 models) for inter-operator variability and 20 pairs (40 models) for intra operator variability. Models were created with a specific version of the software CemrgApp (cemrgapp.com), in which users processed a contrast enhanced magnetic resonance angiogram, and a late gadolinium enhanced (LGE) contrast magnetic resonance (CMR). Two types of simulations were run on each of the 100 processed cases: baseline pacing to calculate local activation time (LAT) maps and atrial fibrillation simulations for which phase singularity (PS) maps were calculated. The openCARP simulator (Plank et al., 2021) was used to run the simulations, using the Courtemance human atrial model with AF electrical remodelling. This dataset contains the labelled surface meshes, output to the CemrgApp software, which in turn are utilised as inputs for the electrophisiological simulations. The dataset is split into 100 folders labelled M1 to M100. Included in file `Cases_and_Users_Paths.csv` is the pairs for each of the comparisons, whether inter- or intra-observer variability.本数据集包含100个左心房模型，所有模型均来源于50名不同患者，被分配至5名操作者中，用于评估操作者间与操作者内变异性。本次数据集划分方案为：30组配对样本（共计60个模型）用于评估操作者间变异性，20组配对样本（共计40个模型）用于评估操作者内变异性。所有模型均通过特定版本的CemrgApp软件（cemrgapp.com）生成，操作者需在该软件中处理对比增强磁共振血管造影（contrast enhanced magnetic resonance angiogram）影像，以及晚期钆增强（late gadolinium enhanced, LGE）对比磁共振（CMR）影像。针对100个已完成处理的病例，共开展两类模拟实验：其一为基础起搏实验，用于生成局部激活时间（local activation time, LAT）图谱；其二为心房颤动模拟实验，需计算相位奇点（phase singularity, PS）图谱。本次模拟采用openCARP模拟器（Plank等人，2021），并搭载带有心房颤动电重构特性的Courtemance人类心房模型。本数据集包含经标注的表面网格模型，其输出格式适配CemrgApp软件，同时可作为电生理模拟的输入数据。数据集以编号M1至M100划分为100个文件夹。文件`Cases_and_Users_Paths.csv`中收录了所有用于操作者间/操作者内变异性对比的配对样本相关信息。
