【摘要】 本文讨论了两个层次上的面向对象技术在辐射投影模拟软件开发中的应用。面向对象的编程语言主要用来简化编码，而系统范围的对象技术方便了较大的辐射投影和断层重建系统的开发。本文分析了对象技术在投影模拟中将遇到的设计、实现和效率问题并提供了一些解决方案。更多还原

【Abstract】 This paper suggests that object oriented technology is particularly applicable in the software implementation of tomographic projection simulation. Two levels of object technology are discussed. Object oriented programming lanuage helps to simpligy design and coding, and system wide object technology facilitates independent developemnt of each component. Some important problems of design, implement and efficientcy that can be encountered in the applicationof object technology in projection simulation are analyzed and possible solutions are provided.
