Very-High-Density Diffuse Optical Tomography System Validation Dataset

This dataset consists of 8 participants completing functional localizer and movie-viewing tasks in both Very High Density Diffuse Optical Tomography (VHD-DOT) and fMRI. Sessions 1 and 2 for each subject include the VHD-DOT data in SNIRF format while sessions 3 or more include the fMRI data in NIFTI format.

Preprocessed fMRI data used for comparisons to VHD-DOT are in the /derivatives folder and are in NIFTI format.

本数据集包含8名受试者，每名受试者均在超高密度漫射光学断层成像（Very High Density Diffuse Optical Tomography, VHD-DOT）与功能磁共振成像（functional magnetic resonance imaging, fMRI）两种成像模态下，完成功能定位任务与电影观看任务并采集到对应数据。每名受试者的第1、2次扫描会话包含SNIRF格式的VHD-DOT数据，第3次及以上扫描会话则包含NIFTI格式的fMRI数据。
用于与VHD-DOT开展对比分析的预处理fMRI数据存储于/derivatives文件夹中，格式为NIFTI。
