Abstract

We propose a method for the segmentation of cerebral sulci, representing them by surfaces. This method is based on the computation of the differential characteristics of MRI data. The computation of curvature information, using the Lvv operator, allows one to differentiate sulcal and gyral regions, resulting in a global detection of the cortical scheme. The analytical description of a particular sulcus is obtained by initializing an active model on its trace upon the brain surface. The result is a surface representing the buried part of the sulcus. The 'snake-spline' model allows one to define an algorithm which is simpler and more robust than the classical snake. This method of segmentation yields good results for the 3D segmentation and visualization of cortical sulci.
