TBSS/UserGuide - Harvard University
In general we recommend using the FMRIB58_FA standard-space image as the target in TBSS. This involves carrying out just one registration per subject and generally gives good alignment results. This option is applied by using the -T flag. Alternatively, you can supply your own target image by using the -t option.

2025年2月19日 · TBSS（Tract-Based Spatial Statistics）是一种用于分析弥散张量成像（DTI）数据的统计技术，它结合了体素和纤维束空间的分析优点。 TBSS通过创建一个代表所有被试纤维束骨架的模板来减少个体间解剖变异的影响。 通过这种方式，TBSS能够在多个被试间实现更精确的比较。 TBSS的核心是骨架提取算法，它首先将所有被试的DTI数据配准到一个共同的空间中，然后从每个体素中提取主要的弥散方向。 接着，TBSS将每个被试的主要弥散方向映射到一个平 …
Introduction to Tract-Based Spatial Statistics (TBSS)
What is TBSS? TBSS is a suite of tools for analyzing diffusion data. This software uses a tensor-fitting method to generate different measures of diffusion, such as fractional anisotropy (FA) and mean diffusivity (MD). Once these measurements are created, you can then extract them using ROI tools like you would for fMRI data.
Acquisition and voxelwise analysis of multi-subject diffusion …
2007年3月15日 · In this protocol, we describe the MRI data acquisition and analysis protocols required for TBSS studies of localized change in brain connectivity across multiple subjects.

2021年3月9日 · 扩散加权磁共振成像（DWI或DW-MRI）是使用特定的MRI序列以及从所得数据生成图像的软件，该软件使用水分子的扩散在MR图像中产生对比度。 组织中的分子扩散不是自由的，而是反映了与许多障碍物（例如大分子，纤维和膜）的相互作用。 因此，水分子扩散模式可以揭示有关正常或处于患病状态的组织结构的微观细节。 弥散张量成像（DTI）是一种特殊的DWI，已被广泛用于绘制大脑中的白质束图。 1. FA数据的三维统计分析. 使用磁共振扩散成像通过测 …
Tract-based spatial statistics: voxelwise analysis of multi-subject ...
2006年7月15日 · TBSS aims to improve the sensitivity, objectivity and interpretability of analysis of multi-subject diffusion imaging studies. We describe TBSS in detail and present example TBSS results from several diffusion imaging studies.
TBSS++: A novel computational method for Tract-Based Spatial …
2023年7月10日 · Diffusion-weighted magnetic resonance imaging (dMRI) is widely used to assess the brain white matter. One of the most common computations in dMRI involves cross-subject tract-specific analysis, whereby dMRI-derived biomarkers …
Methodological considerations on tract-based spatial statistics (TBSS …
2014年10月15日 · TBSS is by far the most popular approach for performing voxel-wise DTI analyses. It provides dedicated processing steps and deals with smoothing and misalignment issues in diffusion MRI-based group analysis studies. However, it also builds upon a certain set of assumptions that we have investigated in detail in this work.
