Background:

Diffusion MR imaging generates extensive streamline data, posing visualization and interpretation challenges.
Existing methods struggle to process large streamline datasets within clinical timeframes.

Purpose of the Study:

To introduce QuickBundles (QB), a novel clustering algorithm for efficient diffusion MR streamline analysis.
To demonstrate QB's ability to generate informative clusters and representative streamlines rapidly.

Main Methods:

Developed a simple, compact, and tailor-made clustering algorithm named QuickBundles (QB).
Utilized centroid streamlines to represent QB clusters effectively.
Performed consistency and robustness tests on the QB reduction method.

Main Results:

QuickBundles (QB) processes large diffusion MR datasets and generates informative clusters in seconds.
QB-generated centroid streamlines provide an effective representation of tractography.
QB reduction demonstrates good consistency and robustness in analyses.

Conclusions:

QuickBundles (QB) offers a computationally efficient solution for handling complex diffusion MR data.
QB facilitates effective tractography visualization, interpretation, and cross-subject similarity analysis.
