Surface Representation and Display of Anatomic Structures From CT-Examinations
Lingfeng Luo · 2005
This paper presents an algorithm for surface extraction, representation and display of anatomic organs or structures (bornes or soft tissues) obtained from X-CT and MRT data which works in a gray- scale 3D image (voxel-based representation) by using two local operators, surface point detector and surface normal estimate, resulting a surface represented by a k-tree structure whose node contains a normal vector at a surface point arid whose are represents neighboring relationship between two surface points. It follows simple computer graphics techniques for fast surface rendering and 3D image manipulation. Some displayed results from X-CT data show images of high quality.
