基于股部CT数据源的虚拟解剖的初步研究

PRIMARY STUDY ON VIRTUAL ANATOMY OF THE THIGH PART ON COMPUTED TOMOGRAPHY DATA SOURCE

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 reconstruct the three-dimensional(3D) image and to study on the virtual anatomy of the thigh part based on computed tomography(CT) data source. Methods Ten patients' contrast-enhanced light-speed CT images of the thigh part were chosen, “3D medical studio” was applied to read CT data, then to reconstruct and anatomize the thigh part. Results The reconstructed 3D images of the thigh part were realistically pseudocolored displayed, it was composed of four kinds of tissues(skin, muscle, skeleton and artery) and could be freely rotated and incised and restored for many times at any shape and depth on real time. Its' layers were distinct among tissues. Conclusion This research realizd partial function of virtual anatomy, it may play a definite role on regional anatomy and sectional image anatomy teaching and clinical radiology diagnosis.
