Abstract:
1. A method comprising: via an information device comprising a graphical user interface, said information device communicatively coupled to a magnetic resonance imaging (MRI) machine: automatically causing a representation of a brain fiber bundle to be rendered, said representation of said brain fiber bundle comprising a plurality of voxels located in an interior region of said brain fiber bundle, each of said plurality of voxels having a negative value of ΔE(x) when ΔE(x) is calculated via: where: ΔE(x) is an energy change function; σ σ 2 is a variance of tensor distances for voxels located in an exterior region; I 0 is an initial approximation of a tensor image; I 1 is a tensor image defined in said interior region; I 2 is a tensor image defined in said exterior region; d is a distance measurement between a pair of tensors; ∇ d is an intrinsic gradient under a metric of a tensor image function Δa(x) is a change in surface area caused by promoting a particular voxel to said interior region; and x represents three dimensional coordinates of a point in Euclidean space, the point directly related to said particular voxel.
