螺旋CT扫描三维立体重建在髋臼骨折的应用

目的　应用螺旋CT三维重建技术揭示髋臼骨折。方法　 15例髋臼骨折患者均行Xvision -GX扫描 ,把所得数据经Sun -Xtension工作站处理 ,采用SSD法和关节分离技术三维重建 ,并把重建图像沿X轴和Z轴旋转显示髋臼。结果　螺旋CT扫描三维重建 15例髋臼骨折均被揭示。而且应用关节分离技术和图像旋转技术能够揭示骨折的细节。结论　通过三维重建技术、关节分离技术和图像旋转技术的联合应用 ,对髋臼骨折的每个细节都能预先直接揭示 ,这对帮助临床选择手术入路和选择合适的内固定方式提供可靠的依据

Using Spiral CT Scanning and Three Dimensional Reconstruction for Acetabulum Fractures

Objective Using spiral CT scanning and three dimensional (3D) reconstruction technique to reveal acetabulum fractures.Methods Fiften cases of acetabulum fractures were scanned with Xvision GX spiral CT scanner,and the data obtaines were treated in Sun Xtension word station for 3D reconstruction,with shaded surface display technique,Joint Separation technique and image-rotation round X and Z axes.Results Spiral CT scanning 3D reconstruction may not only reveal acetabulum fractures of all patients but also show every detail of acetabulum fractures in 3D images of all patients.Conclusion With the combination of 3D,joint separation and image rotation technique,every detail of and complex fracture can be pereceived directly and distinctly,3D reconstruction is helpful in designing operative approach and internal fixation method.
