Advanced fiber tracking and medical navigation in a brain

摘要

A method for finding fibers in image data of a brain, comprising the steps of: matching (S2) a functional atlas of the brain to an image data set which represents a medical image of the brain; performing functional atlas segmentation (S3) in order to segment the image data set into functional areas; using (S4, S8) the segmented image data set to determine at least one seed point for a fiber tracking algorithm; and - performing (S5) fiber tracking in order to find the fiber.

1. A method for finding a fiber in image data of an associated physical brain, the method comprising:
storing in a non-transient memory storage medium a functional atlas of a generic brain, wherein an atlas structure represented by the functional atlas comprises the generic brain divided into one or more functional areas rather than into physical components or areas, each of the one or more functional areas being representative of a set of neurons which provide a specific function of the generic brain: matching the functional atlas of the generic brain to an image data set which represents a medical image of the associated physical brain, the matching comprising adapting a geometry of the functional atlas of the generic brain such that the functional atlas as an adapted functional atlas matches the physical brain in the image data set; performing functional atlas segmentation in accordance with the adapting of the functional atlas to the adapted functional atlas to segment the image data set into the one or more functional areas of the associated physical brain resulting in a segmented image data set; determining at least one seed point in the segmented image data set for use by a fiber tracking algorithm; and performing fiber tracking in the image data, using the fiber tracking algorithm and the at least one seed point, to find the fiber by tracking the fiber step-by-step starting from the seed point.
