Description: 数字影像重建在基于灰度的2D／3D医学图像配准技术中具有重要作用。它是利用基于射线追踪算法从三维数据如CT中获得二维虚拟x线图像。影像重建结果的质量直接影响到配准结果的精度。本文对数字影像重建技术作了一定的探讨，实现了对cT体数据的数字影像重建，并通过增强技术获得了突出骨组织的图像，为后续的配准研究做了很好的准备工作。-Digital image reconstruction in intensity based 2D/3D medical image registration techniques have an important role. It is the use of ray-tracing algorithm based on the data from the three-dimensional CT obtained as two-dimensional virtual x-ray images. Image reconstruction quality of the results directly affect the accuracy of registration results. In this paper, digital image reconstruction techniques were explored certain to achieve volume data on the number of cT image reconstruction, and by enhancing technology to obtain a prominent image of bone tissue, for follow-up studies with prospective done a very good preparations.

Description: 医学图像三维重建的主要步骤包括医学图像的获取、预处理、组织器官的分割
与提取、形成体数据库、三维模型的重建等。其中图像预处理是三维图像重建系统
的首要环节也是关键步骤，预处理的结果直接影响到分割效果，而目标分割的质量
直接决定系统重建的整体效果。本文主要完成的研究工作如下:
-3D medical image reconstruction steps include medical image acquisition, preprocessing, tissue and organ segmentation and extraction, and the formation of body database, the reconstruction of three-dimensional model. Including image pre-processing is also a key step is the most important part of the three-dimensional image reconstruction system, the the pretreatment result of segmentation results directly affect, object segmentation directly determine the quality of the overall effect of the system reconstruction.
