Description: 医学图像配准，2D_3D医学图像配准论文-In 2D-3D Medical Image Registration (MIR), preoperative 3D CT images are registered
with intraoperative 2D X-rays images obtained by fluoroscopy or Electronic Portal Imag-
ing Devices (EPID). 2D-3D MIR is established by computing Digitally Reconstructed Ra-
diograph (DRR) images rendered from the volumetric data and is useful in many med-
ical procedures where surgical planning is undertaken using volumetric data prior to
treatment, such as in radiation therapy treatment and image guide surgery. The conven-
tional approach used to render DRR images is a computationally expensive process and
forms a bottleneck in 2D-3D MIR. This paper evaluates the registration performance of
a 2D-3D MIR system which attempts to improve the rendering performance by reduc-
ing the number of intersections between the rays cast and internal spaces within the CT
volume by using an Octree compression. An Octree compressed CT volume comprises
fewer internal spaces, each containing voxels which shar

Description: 八叉树（Octree）的定义是：若不为空树的话，树中任一节点的子节点恰好只会有八个，或零个，也就是子节点不会有0与8以外的数目。-Definition octree (Octree) is: If the tree is empty, then any tree node s children will have exactly eight, or zero, that is, the number of child nodes 0 and 8 will not have outside.

Description: 利用地球立体剖分格网生成SubdivisionR_树索引模型
针对三维数据管理中八叉树索引冗余多、R-树索引插入删除过程复杂的问题,依托GeoSOT地球立体剖分格网,提出了一种新的八叉树与R-树有机结合的Subdivision R-树索引模型(Subdivision R-tree)。首先,以GeoSOT地球立体剖分格网八叉树索引为基础构建了Subdivision R-树索引模型结构 随后,设计了Subdivision R-树索引模型基本的插入、删除、查询、分析算法 最后,开展了Subdivision R-树索引与原有数据索引性能对比试验,并对Subdivision R-树的阈值选取进行了相应分析。

First, the Earth' s perspective GeoSOT octree subdivision grid based index constructed Subdivision R- tree indexes model structure subsequently, the basic design of the insertion Subdivision R- tree indexing model, delete, query, analysis algorithm and finally, to carry out Subdivision R- tree indexes with the original data indexing performance comparison test, and the threshold Subdivision R- tree analysis of selected accordingly.
