Materials and Methods: 75 patients were scanned transversally by GE Lightspeed Plus Multiple Slices Scaner .

材料和方法：应用GELightspeed Plus多排螺旋机扫描仪，对75位病例进行筛窦横断面扫描，通过GE W4.0工作站，在三维重建软件支持下作冠状位图像重建。

Methods Thirty-nine cases of the craniofacial fracture were scanned transversally and thin-layer reconstructed the images by GE Lightspeed 16 CT scanner.The reconstructed data included standard reconstitution and bony reconstitution.

应用GE Lightspeed 16螺旋CT机，对39例颅面部骨折的患者行轴位扫描，对所得数据进行薄建，并对原始数据行标准重建和骨重建，分析其结果。

ABSTRACT A Clinical and Experimental Study on Trifocal Distraction Osteogenesis for Reconstruction of Segmental Mandibular Defects

探讨三焦点牵引成骨技术在下颌骨骨段缺损功能性重建中的应用，研究三焦点牵引成骨的成骨规律、特点和重建骨种植义齿修复的可行性。

Result: All post process images that obtain from the SCT show 35 patients with wrist vessel bone fracture, 3 patients with Os trigonum fractures, 1 patient with Os trapezium fractures.

结果：全组病例的薄层重建及三维重建显示腕舟骨骨折35例，合并舟骨月骨周围脱位8例；三角骨骨折3例，大多角骨骨折1例。

But the 3D CT images were less satisfactory for undisplaced fractures. multi planar reconstruction was the valid complement for it.

然而三维CT重建对无移位的髋臼骨折显示不满意，二维重建是对其有效的补充。

The technique of SSD and MPR with Dual-slice spiral CT scanning may obtain the images which can satisfy clinical necessity. This 3-D images in combination with section may supply vast information about impacted teeth in maxilla clinically. It can be used as one exact examining instrument for treatment. maxilla unerupted teeth; spiral CT; 3-dimensional reconstruction

双排螺旋CT表面遮盖法和多平面重建技术能获得满足临床需要的三维图像和多平面重建图像，联合断面图像可为临床提供上颌埋伏牙的大量信息，可作为埋伏牙治疗进一步的精确检查手段。

Axial multi-planar reconstruction of the stents and curved-planar reconstruction through the stents were evaluated for image quality on a 5-point scale (1=excellent,5=uninterpretable) and lumen diameter.

采用5分制计分法评价支架的轴位多平面重建图像及通过支架内腔中心的曲面重建图像质量，同时测量支架内管腔直径。

The characteristics of image moments can be applied in manyfields. We apply Tebechbief moment characteristic to match replace of using graycharacteristic as primitives. An area moment has the property of unsensitive to transition,rotation and sealed change of area, the property of area moment is applied in the areamatching approach in our thesis, combined with a new constraint, and a novel area-basedmatching approach is proposed.

文中对Tchebichef正交矩能对图像进行精确重建的原理，利用点矩特征作为匹配基元对图像进行匹配，得到了较好的效果，并讨论了利用图像重建误差图像进行匹配的可能性和有效性；最后通过矩对区域的平移、旋转和尺度变化的不敏感特性，讨论了基于不变矩的区域匹配方法，通过引入相对位置约束提出了一种新的匹配策略。

This paper presented an adaptive 3D fractal reconstruction algorithm to overcome the shortcomings of conventional methods, such as time consuming, ununiformity, parametric complexity.

针对常规三维分形地形重建算法具有的速度慢、插值点分布不均匀、参数设置复杂等缺点，提出自适应的三维分形地形重建算法。

They told us that China had received a lot of funds from all over the world since the earth quake, so he welcome us to withness the rebuilding of Chen Jia Ba. He even took a picture of Annike and me.

他们说世界各地的捐款对灾区重建帮助很大，所以非常欢迎我们来考察重建的工作，还热情地跟我和Annike拍了一张照。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
