TL;DR: In this article, a method for extracting geometrical characteristics of an image in a lesion area and a related product is proposed, which comprises the following steps: acquiring three-dimensional image data of a lung lesion region, generating a two-dimensional grid formed by connecting a plurality of vertexes according to the three-dimensions image data, segmenting the two dimensional grid into two topological discs by using a closed curve formed by partial vertexes in the plurality, mapping the two topology discs to the two unit rectangles respectively, determining pixel values of corresponding points

TL;DR: In this paper, a method for processing a lung lesion area image and a related product is presented, which comprises the following steps: acquiring three-dimensional image data of a lung lesions area, generating a tetrahedral mesh formed by connecting a plurality of vertexes according to the 3D image data, determining a geometric characteristic value at the vertex, and replacing the voxel value with the geometric feature value to realize extraction of the geometric features of the lung lesions.
