数字化体层摄影在骨关节系统中的应用

The application of digital tomosynthesis in the system of skeletal and joint

X线摄影是在二维图像上显示三维结构,组织的结构和密度在影像上重叠,给诊断增加了一定的难度。数字化体层摄影是一种新的断层摄影技术,是以传统体层摄影的几何原理为基础,结合现代数字电子技术尤其是计算机图像处理技术研发的新型体层成像方法。本篇综述将对数字化体层摄影发展及原理做简单介绍,旨在探讨其在骨关节系统中的应用,为临床医生在骨关节疾病诊断中进一步提供新思路。

X-ray photography uses its penetration to display the three-dimensional structures in the two-dimensional films, which leads to easily making the overlap of structures and density in images, so that it is difficult to diagnose. Digital tomosynthesis is a new tomography method, which is based on the geometric principles of conventional tomography and combines with modern digital electronic technology, especially computer image processing technology. This review briefly describes the development and principle of digital tomosynthesis, and then discusses its application in skeletal and joint systems, furthers studying of which will contribute to providing new ideas for clinicians＇ diagnosis.
