摘要目的 构建一组能在个人电脑(PC)上高速运行的三维可视化数字骨科临床研究平台系统.方法 2007年1月至2009年6月,收集三组资料,包括:自多层螺旋CT机图像工作站导出的300余例涉及骨创伤、关节、脊柱、骨肿瘤患者的薄层原始数据(DICOM格式);部分应用较为广泛的内置入物器械原型;20名健康志愿者(男10名,女10名;年龄21～30岁,平均24.5岁)的全身多层螺旋CT机扫描后的薄层原始数据.应用计算机及信息通讯领域的前沿技术,通过改进算法、改进人机交互方式、软硬件性能优化及相关逆向工程技术,创建一组能容纳海量数据及便于临床医牛广泛参与的数字化骨科临床研究平台软件包.结果 通过整合交叉学科前沿技术及大量的创新性工作,创建多功能数字化骨科临床研究平台,并将其命名为Superlmage系统.Superlmage系统能在目前丰流配置的PC上高速运行,自由编辑,兼容Windows XP/Vista、Unix及Linux等操作系统,数据读取支持主流品牌CT机导出的DICOM3.0标准数据,并实现了高精度的三维霞建成像;伪彩渲染的多平面重组成像;高速、便捷的三维图像交互式分割及编辑.SuperImage系统还附带一组信息丰富的数字化资料库,包括三维数字化骨骼、数字化内置人物虚拟模型器械库及患者数字化信息资料库,且支持数字化远程动态信息交互.结论 数字化骨科临床研究平台可满足临床医生的日常工作及科研需求,如精准的术前设计、术后随访、高败的数字化资料管理、远程信息交互、仿真的数字化虚拟教学及部分数字骨科解剖学研究等.

abstractsObjective To study and develop a digital 3D orthopaedics imaging software that can be efiqciently used on today's main-stream personal computers.Methods From January 2007 to June 2009,including 3 sets of more than 300 clinical multi-slice CT images involving orthopaedics trauma,joint,spine,orthopaedics tumor;a few interstitial implants with applied generally;and also full body multi-slice CT images of 20 healthy volunteers.There were 10 males and 10 females with an average age of 24.5 years (ranged from 21 to 30 years).By adapting latest image processing algorithms,interactive graphics methods,and reversing engineering and hardware software optimization techniques,a digital orthopaedics platform was created,which allowed user to interactively manipulate,display large.volume DICeM data produced by clinical CT scans in 3D.Results Through inter-disciplinary efforts of medical and computer experts,the new system was created and named as Superlmage system,which was able to achieve interactive speed on today's main-stream personal computers.Function included hi-resolution 3D surface and volume rendering,interactive segmentation in 3D,editing,color MPR,operation simulation etc.Superlmage system also included a rich reference database,full body digital bones,virtual models of interstitial implants,and patient database.The system also supported remote data sharing and interaction between different installations.Conclusion PC based digital 3D orthopaedics imaging software can help clinical doctors,medical students and researcher in many areas including diagnosis,treatment planning,patients' follow-up and clinical research.That also gives doctors an effective tool for distributable store,share,manage medical image data,and assist in education and digital human anatomy study.
