Volume-based and surface-based algorithms for three-dimensional rendering of computed tomography (CT) scans of the human skull were compared in patients with craniofacial anomalies. Both methods were applied to a selected sample of 12 clinical CT studies. The number of sections ranged from 24 to 72 and the section thickness from 1.5 to 6.0 mm. Volume renderings were more prone to interpolation artifacts but captured the anatomy in greater detail. The sites of closed cranial sutures, visualized using the volume technique, were not demonstrated using the specific surface rendering technique used in this study. In both techniques the areas of thin bone appeared as gaps.
在颅面畸形患者中，对基于体积和基于表面的算法用于人类颅骨计算机断层扫描（CT）三维重建进行了比较。两种方法都应用于12项临床CT研究的选定样本。切片数量从24到72不等，切片厚度从1.5到6.0毫米。体积重建更容易出现插值伪影，但能更详细地捕捉解剖结构。使用体积技术可视化的闭合颅骨缝线部位，在本研究使用的特定表面重建技术中未显示出来。在两种技术中，薄骨区域都表现为间隙。
