| 摘 要： | <正> 本文提出一种物空间多目标体素的灰度线段表示法及象空间双动态屏幕技术,利用动态数据结构,得到一种在2D 屏幕上同时快速显示多个目标3D 图象的方法,并利用透明原理,实现了内、外目标间的透明显示。本方法可用于医学断层图象序列中多个目标的3D 显示。文中给出几种不同旋转角度 CT 断层图象序列中肝脏、肿瘤及血管等多目标的3D 显示结果。

| Abstract: | In this paper,we propose a rapid method of display realistic images of 3-dimensional multiobject on a 2-dimensional display screen simultan- eous.We propse a new objects representation format called “gray-scale segments”to represent the multiobject voxel array.using the double dynamic screen technique which we propose here and dynamic data structure,3D display of multiobject are realized.The theorem of transparency is used to realize the displaying of transparent object. Results from applying this display technique to CT data with different rotation angle of multiobject such as liver,tumor and vessels are presented. |
