摘要: 探讨了大脑表面形态提取的一种新方法——可变形表面模型。脑表面形态的提取是脑的可视化、形态学分析、脑图像配准等多种工作的基础。对于多层MR脑图像,应用可变形表面算法,可以较准确地获得脑外部皮质的参数化表示。该算法对噪声具有一定的鲁棒性,并对于不同的外部形态具有较大范围的适应性。

Abstract: As a new method to map the outer cortex of the human brain, a deformable surface model is described in this paper. Obtaining the shape of the brain is an important step for shape visualization, morphological analysis and registration of brain images.Using the deformable surface algorithm on three dimensional MRimages a parametererization of the central layer of the outer cortex can be obtained. This algorithm combines robustness to noise with flexibility to represent a broad class of shapes.

Key words: deformable surface, cortex, magnetic resonance image
