There are two reconstruction methods for 3D imaging with a helical scanner: a surface rendering process providing a 3D-SSD (Surface Shaded Display) image that looks like a plaster cast skull and 3D-VRD (Volume Rendering Technique) which is more precise and gives 3D images similar to radiographs. We review briefly the techniques used to acquire these images and present 3D volume-rendering scanners, pointing out its usefulness in craniomaxillofacial traumatology and reconstructive surgery.
一种是表面渲染过程，可提供类似石膏铸型颅骨的三维表面阴影显示（3D-SSD）图像；另一种是三维容积再现技术（3D-VRD），它更精确，能给出类似于X光片的三维图像。我们简要回顾获取这些图像所使用的技术，并介绍三维容积再现扫描仪，指出其在颅颌面创伤学和重建手术中的用途。
