Stereolithography, a new technique of prototype fabrication developed for the aerospace industry, offers a unique way to display patient anatomy. Like current computer aided design (CAD) systems, it uses digital image data from computed tomography (CT) and magnetic resonance (MR) to produce a physical model. Unlike conventional CAD it does not require a cutting tool and, therefore, CAD toolpath limitations do not exist. The stereolithography apparatus uses an ultraviolet laser to selectively polymerize and solidify a polymeric liquid plastic solution under computer control. The device was used to produce a model of cranial bony anatomy from CT image data, providing full internal detail in the constructed model, including encased sinuses, foramen, and potentially complete internal anatomy within a closed skull. The advantages and disadvantages of this technology are reviewed with an emphasis on future development.
立体光刻技术是为航空航天工业开发的一种新型原型制造技术,它提供了一种展示患者解剖结构的独特方式。与当前的计算机辅助设计(CAD)系统一样,它使用来自计算机断层扫描(CT)和磁共振(MR)的数字图像数据来生成物理模型。与传统CAD不同的是,它不需要切割工具,因此不存在CAD刀具路径限制。立体光刻设备使用紫外激光在计算机控制下选择性地聚合和固化聚合液体塑料溶液。该设备用于从CT图像数据生成颅骨解剖模型,在构建的模型中提供完整的内部细节,包括封闭颅骨内的鼻窦、孔以及潜在的完整内部解剖结构。本文回顾了该技术的优缺点,并重点讨论了其未来发展。
