Abstract:

We present a novel unified framework for explicitly parameterizing white fiber tracts using a Fourier series expansion. Unlike available spline models, the proposed method does not have internal knots and explicitly represents the tract as a linear combination of basis functions. With further development, these parametric tract shape measures can be used to perform automatic tract extraction, characterization of tract morphologic shape in different population groups, and multiple subject spatial normalization and tract segmentation.
