Deterministic fiber tracking
WebFurther, probabilistic fiber tracking has been shown to be superior to deterministic tracking methods in multiple studies comparing both methods in white matter tracking, mainly concerning smaller fiber bundles.10,11,15 To compensate for the supposedly higher levels of uncertainty in the area of CSF-filled basal cisterns, we

WebDeterministic maximum direction getter is the deterministic version of the probabilistic direction getter. It can be used with the same local models and has the same parameters. Deterministic maximum fiber tracking follows the trajectory of the most probable pathway within the tracking constraint (e.g. max angle).
