With the increasing use of medical imaging in forensics, as well as the technological advances in rapid prototyping, we suggest combining these techniques to generate displays of forensic findings. We used computed tomography (CT), CT angiography, magnetic resonance imaging (MRI) and surface scanning with photogrammetry in conjunction with segmentation techniques to generate 3D polygon meshes. Based on these data sets, a 3D printer created colored models of the anatomical structures. Using this technique, we could create models of bone fractures, vessels, cardiac infarctions, ruptured organs as well as bitemark wounds. The final models are anatomically accurate, fully colored representations of bones, vessels and soft tissue, and they demonstrate radiologically visible pathologies. The models are more easily understood by laypersons than volume rendering or 2D reconstructions. Therefore, they are suitable for presentations in courtrooms and for educational purposes.
随着医学成像在法医学中的应用越来越多，以及快速成型技术的进步，我们建议将这些技术结合起来，以生成法医发现的显示。我们使用计算机断层扫描 (CT)、CT 血管造影、磁共振成像 (MRI) 和摄影测量表面扫描，并结合分割技术生成 3D 多边形网格。基于这些数据集，3D 打印机创建了解剖结构的彩色模型。使用这种技术，我们可以创建骨折、血管、心肌梗死、破裂器官以及咬痕伤口的模型。最终模型是骨骼、血管和软组织的解剖学上准确、完全着色的表示，并且它们显示了放射可见的病理学。与体积渲染或 2D 重建相比，模型更容易被非专业人士理解。因此，它们适用于法庭陈述和教育目的。
