Conventional three-dimensional imaging uses thresholding, or surface rendering technique, which limits accuracy and detail, and hinders soft tissue definition. Volumetric image rendering preserves all CT data, not just surface boundaries, and therefore overcomes these limitations. Three-dimensional images thus generated can be used for muscular and vascular anatomy as well as skeletal structures, with preservation of subtle detail. Representative cases are used to illustrate this technique and its implications for therapy and plastic and reconstructive surgery.
传统的三维成像使用阈值处理或表面渲染技术，这限制了准确性和细节，并阻碍了软组织的定义。容积图像渲染保留了所有CT数据，而不仅仅是表面边界，因此克服了这些限制。由此生成的三维图像可用于肌肉和血管解剖以及骨骼结构，同时保留细微细节。通过代表性病例来说明该技术及其对治疗以及整形和重建手术的意义。
