Background:

White matter tract segmentation is crucial for analyzing brain connectivity.
Existing methods face challenges in speed, consistency, and generalization.

Purpose of the Study:

To develop a deep learning method (DeepWMA) for fast and consistent segmentation of 54 major white matter tracts.
To evaluate DeepWMA's accuracy, consistency, and generalizability across diverse populations and data types.

Main Methods:

Creation of a large-scale dataset with 1 million labeled fiber samples.
Development of a novel 2D multi-channel feature descriptor (FiberMap).
Training a convolutional neural network (CNN) fiber classification model.

Main Results:

Achieved 90.99% classification accuracy on training data.
Demonstrated over 99% successful tract identification across diverse populations (neonates to elderly, healthy to patients).
Showed good generalization to tractography data from multiple tracking methods.

Conclusions:

DeepWMA offers a fast, efficient, and highly consistent tool for white matter segmentation.
The method shows robust performance across varied demographics and health conditions.
DeepWMA advances the analysis of large diffusion MRI tractography datasets.
