Methods of three-dimensional analysis of axial computed tomographic images have recently been described. Mostly, reports have concentrated on applications relative to congenital deformities. In this report, one method of three- dimensional reformatting is reviewed. Images formed by this method have solid surface appearance and can be color enhanced and manipulated to isolate anatomic structures of interest. The program allows mathematical quantitation of tissue densities, volumes, and distances. Furthermore, models and implants can be easily made using the programs CAD-CAM ability. These images and models can be generated from data obtained on the most common CT units without any modifications. This report emphasizes maxillofacial applications other than those previously reported in the surgical and radiological literature.
近期已有关于轴向计算机断层扫描图像三维分析方法的描述。大多数报告集中于与先天性畸形相关的应用。在本报告中，对一种三维重新格式化方法进行了综述。通过该方法形成的图像具有实体表面外观，可进行色彩增强和处理以分离感兴趣的解剖结构。该程序允许对组织密度、体积和距离进行数学定量分析。此外，利用程序的计算机辅助设计与制造（CAD-CAM）功能可轻松制作模型和植入物。这些图像和模型可从最常见的CT设备获取的数据生成，无需任何修改。本报告强调了颌面应用，这些应用不同于先前外科和放射学文献中所报道的。
