目的　研究利用股部的CT数据进行三维重建和初步的虚拟解剖。　方法　 10例临床病人股部Light speedCT增强扫描的原始数据 ,利用“医学三维图像工作室”软件系统对其进行读取、三维重建和虚拟解剖。　结果　重建出的股部图像逼真 ,分皮肤、肌肉、骨骼和动脉等 4类器官伪彩显示 ,相互间结构层次清晰 ,能实时旋转、任意厚度多次切割。　结论　本研究实现了虚拟解剖的部分功能 ,对局部解剖和断层影像解剖学教学以及临床影像诊断具有明确的辅助作用。

Objective To study the three-dimensional reconstruction and preliminary virtual anatomy using the CT data of the thighs. Methods Light speedCT enhanced the original data of 10 cases of clinical patients, and read, reconstruct and virtualize the images by using the medical 3D imaging studio software system. Results The reconstructed image of the femoral part was vividly displayed by four types of organs such as skin, muscle, bones and arteries. The structures of the four parts were clearly structured and could be rotated in real time and cut at any thickness for many times. Conclusions This research has realized some functions of virtual anatomy and has a clear auxiliary effect on the teaching of local anatomy and tomography anatomy and clinical imaging diagnosis.
