摘要

本文提出了一种利用单一模型从头部MR图像中分割脑体积和皮层表面的新方法。该方法基于原始的可变形模型，该模型可以使用基于细胞复合体的表示来联合处理体积和表面。该模型在大脑外表面初始化，然后在保持拓扑结构的同时，根据体积和表面约束在皮层褶皱内变形。

Joined segmentation of cortical surface and brain volume in MRI using a homotopic deformable cellular model

The paper presents a novel method to segment both the brain volume and the cortical surface from a MR image of the head using a single model. This method is based on an original deformable model which can handle jointly volumes and surfaces using a cellular complex based representation. The model is initialized on the outer brain surface and then deformed inside the cortex folds according to both volumic and surfacic constraints, while preserving topology.
