利用快速原型技术构建医学模型

Rapid prototyping－ oriented medical model modeling

三维医学模型在医学领域有着广泛的用途，也给人类带来巨大的利益。 CT或 MRI扫描原理与快速原型技术的基本原理从逻辑上是一致的，数据格式转换和建模是这两种先进技术结合的关键问题。本文通过实例，分析了 CAD系统在建立医学模型时存在一定的缺陷。面向医学模型的 CT模型软件系统不仅能与 CT扫描机直接接口，而且能与快速原型机和 CAD系统直接接口，并能快速、准确地加工出医学模型。

3D medical models have many uses in medicine and bring human being huge profits. The scanning principle of CT or MRI and the fundamental principle of RPT are logically accordant. Data format conversion and modeling are a key of integrating this two advanced technologies. In this paper, CAD systems will be analysed through an example, and their shortcoming presents itself in a certain extent when they are used to build a medical model from CT scanned data. The medical model－ oriented CT modeller System can directly interface not only with a CT scanner but with RP or CAD systems, and a medical model can rapidly and accurately be manufactured via it.
