| 摘 要： | 目的探讨多层螺旋CT(multi-slice computed tomography,MSCT)及三维重建技术在交通事故损伤生物力学分析方面的应用价值。方法以真实案例为基础,通过MSCT扫描获得尸体断层影像,进行三维图像重建,结合尸体解剖、车辆勘验等结果综合分析交通事故撞击、碾压和挤压等行为方式中的生物力学过程,并与尸体解剖结果进行对比。结果 MSCT和三维重建获得了不同受力部位骨折的位置、骨折线走向以及骨内碎裂状况等原位特征,其对于骨折的精细还原优于尸体解剖。结论 MSCT和三维重建技术在原位特征的再现、图像的易操作性以及证据的保全等方面凸显优势,可对道路交通事故损伤生物力学分析起补充和引导作用。 |

| Abstract: | Objective To study the application value of multi-slice computed tomography(MSCT) and 3D reconstruction in biomechanical analysis of traffic accidents in forensic medicine.Methods Based on a real case,the tomoscan images were obtained from a corpse by MSCT scanning.The 3D images were reconstructed.The biomechanic process of injury manners of impacting,rolling and crushing in traffic accidents was analyzed together with autopsy,vehicle inspection,etc.The MSCT results were compared with the autopsy results.Re... |
