Paper Abstract

Studies of shape, degree of folding and variability of the surface of the brain can be found as early as 1967. Measuring shape and degree of folding from radiological images is, however, a relatively recent development. Our objective is to develop a framework for the study of the shape and geometric properties of the brain surface from radiological images for the purposes of studying abnormalities of cortical folding. The construction of an explicit surface model allows the calculation of local measures of intrinsic curvature and folding, and provides a means of studying connectivity and shape variation. To speed up these calculations, we have developed a surface simplification method for discrete data representing surfaces derived from MR images. This method facilitates the calculation of these measures of interest while preserving the essential features of the surface in high curvature regions.
