Porous high-density polyethylene, one of the commercially available alloplasts, has been success fully used in nasal reconstruction for more than ten years. This study presents our experience with PHDPE in the reconstruction of traumatic saddle nose deformities.

本研究报告运用颅颜重建手术使用的一种人工合成异体填充物，多孔高密度聚乙烯(porous high-density polyethylene， PHDPE， Medpor)，重建创伤性马鞍鼻的经验。

The 3D wavelet sampling theorem has been obtained from 1D wavelet sampling theorem using scalar product method and then it is used to improve ART in direct volume reconstruction. In the other hand, the 1D wavelet sampling theorem is applied for the analytic direct reconstruction algorithm too.

散乱数据点的重建网格大多数基于三角形网格，对于规模较大的数据点集，重建网格的面片数目过多，不能满足实时处理的要求。

For computer simulation of our new reconstruction algorithm, which is only valid for some special scatterers, the corresponding direct scattering data are indispensable and some are given for several scatterer models out of such consideration.

进行重建计算机模拟计算，需要正散射数据，又因本文给出的重建算法目前只对满足特定条件的散射体才有效，出于这样的考虑，这里给出了若干形状不太复杂的散射体对平面波的散射。

A high-speed 3-D reconstruction algorithm for semitransparent specimen,named blend fluorescence algorithm based on B-Spine, is presented.

S.From all the patients with MB-MCA and whose MCA were encased by the myocardium completely,30 patients were choosed randomly,their datasets were reconstructed seriatim by every 5%R-R interval,the whole cardiac cycle were reconstructed by 20 phases,the diameter of the mural coronary arteries of every phase was reviewed and measured,the phases were found out where the diameters were maximal and minimal,the systolic compression rate was calculated,Pearson correlation analysis was used to analyze the relation between length,depth,and degree of systolic compression of the mural coronary artery.

s表示。在所有存在MB-MCA并且MCA被心肌完全包饶的病例图像中，随机抽取30例图像的数据，以每隔5%R-R间期为一个重建时相，对每个病例0.100%整个心动周期分20个期相进行重建，观察并测量MCA在整个心动周期中管径的变化，探索管径最大和最小时的时相显示规律，计算MCA最大狭窄程度，应用Pearson相关统计分析MCA狭窄程度与MB的长度及厚度之间的相关关系。
