我们在这里提出一种旨在在皮质表面定义基于表面的坐标系的方法。在神经成像框架中，皮层定位和受试者间匹配都需要这样的系统。我们提出了一种基于每个半球灰/白质界面的球形拓扑以及使用自然组织和可再现的解剖特征的自动参数化。从用作初始约束的那些标记，坐标系通过在皮质表面上求解的偏微分方程来传播。
We present here a method that aims at defining a surface-based coordinate system on the cortical surface. Such a system is needed for both cortical localization and intersubject matching in the framework of neuroiniaging. We propose an automatic parameterization based on the spherical topology of the grey/white matter interface of each hemisphere and on the use of naturally organized and reproducible anatomical features. From those markers used as initial constraints, the coordinate system is propagated via a PDE solved on the cortical surface.
