Abstract Nowadays, image processing and 3D shape analysis are an integral part of clinical practice and have the potentiality to support clinicians with advanced analysis and visualization techniques. The main contribution of the paper is the integration of these two approaches in order to increase the amount of information available and, thus, allow a more accurate analysis of each patient. Given a segmented anatomical district, we propose a novel mapping of volumetric data onto the segmented surface. The grey levels of the image voxels are mapped through a volume-surface correspondence map, which defines a grey level texture on the segmented surface. The resulting texture mapping is coherent to the local morphology of the segmented anatomical structure and provides an enhanced visual representation of the anatomical district. The integration of volume-based and surface-based information in a unique 3D representation also supports the identification and characterization of morphological landmarks and pathology evaluations.

通过灰度映射分析 3D 分割解剖区

摘要 如今，图像处理和 3D 形状分析是临床实践中不可或缺的一部分，有可能为临床医生提供先进的分析和可视化技术。这篇论文的主要贡献是整合了这两种方法，以增加可用信息量，从而对每位患者进行更准确的分析。给定一个分割的解剖区，我们提出了一种将体积数据映射到分割表面的新方法。图像体素的灰度级通过体积-表面对应映射映射，该映射定义了分割表面上的灰度级纹理。由此产生的纹理映射与分割解剖结构的局部形态相一致，并提供了解剖区的增强视觉表示。
