Personal computer (PC)-based computing is now ubiquitous in common consumer applications. Although PCs have equaled or surpassed engineering workstations in basic computing power and economy, there is still strong workstation dependency for imaging applications. This article demonstrates that a complete system, based on a Pentium PC (Intel Corporation, Santa Clara, CA) and readily available and inexpensive software, can be built very economically for effective execution of most of the commonly used three-dimensional imaging operations. For the craniofacial application, the Pentium system offers a twofold speed advantage over a Sparc 20 system using similar three-dimensional processing software. The Pentium system allows interactive fuzzy volume rendering, and manipulation and analysis of complex hard and soft-tissue structures.
基于个人计算机（PC）的计算如今在普通消费应用中无处不在。尽管个人计算机在基本计算能力和经济性方面已等同于或超过了工程工作站，但在成像应用方面仍严重依赖工作站。本文证明，基于奔腾PC（英特尔公司，加利福尼亚州圣克拉拉）和现成且廉价软件构建的完整系统，能够以非常经济的方式构建，以有效执行大多数常用的三维成像操作。对于颅面应用，奔腾系统在使用类似三维处理软件时，比Sparc 20系统具有两倍的速度优势。奔腾系统允许交互式模糊体绘制，以及对复杂的硬组织和软组织结构进行操作与分析。
