Abstract

We consider the application of segmentation based on cluster classification techniques to a series of images derived from the diffusion tensor. The extension of a sophisticated cluster simulation tool used for optimizing data acquisition for such segmentation methods to diffusion-based images is described. The characteristics of a variety of diffusion-based images including fractional anisotropy images, diffusion tensor trace images, and isotropically diffusion-weighted images are considered and their application to neurological image segmentation is investigated. The critical effect of the signal-to-noise ratio on fractional anisotropy is analyzed and limitations of current echo planar-based strategies are discussed. Segmentation is shownto be possible using only images derived from the diffusion tensor, and such images are shown to offer exciting new avenues for neurological segmentation.
