医学CT图像三维可视化系统的研究与开发

为开发符合医学数字成像与通讯(DICOM)标准的医学计算机断层扫描(CT)图像三维可视化系统,探讨了DICOM文件系统的结构和解析方法、医学CT图像窗宽/窗位调节技术及其三维可视化算法,描述了系统的结构和各功能模块的实现方法.通过对医学CT图像三维可视化软件的开发,比较了表面绘制和体绘制的特点,成功而有效地实现了符合DICOM标准的医学CT图像的三维可视化,为影像诊断提供了形象直观的技术方法,具有广泛的临床应用价值.

Research and Development a Visualization System for Medical CT Images

In order to develop a 3D visualization system for medical CT images which comply with DICOM standard, the authors study DICOM file format and methods of analyzing it, discuss the key technology of adjusting Windows Center/Windows Level of Medical CT images and 3D visualization methods, and describe the system's structure and approaches to implement every function module. Through developing 3D reconstruction software of medical CT images, surface rendering is compared with volume rendering.We succeed in implementing the visualization system for medical CT images which comply with DICOM standard. This system provides an intuitionistic way for diagnosing with medical images. The system is significant in clinical environment.
