简介：AbstractPurpose:This study aimed at exploring the application of trauma time axis management in the treatment of severe trauma patients by using the Medicalsystem trauma system.Methods:We performed a retrospective cohort study involving patients with severe trauma. Patients who were admitted before the application of the Medicalsystem trauma system were divided into before system group; patients who were admitted after the application of the system were divided into after system group. Comparison was made between the two groups. For normally distributed data, means were reported along with standard deviation, and comparisons were made using the independent samples t test. Categorical data were compared using the Chi-square test. The Mann-Whitney U test was used to compare nonparametric variables.Results:There were 528 patients admitted to the study during the study period. There was no significant statistical difference in the time from the start of trauma team to arrive at the resuscitation room between the two groups. The time from arrival at hospital to endotracheal intubation, to ventilator therapy, to blood transfusion, to completion of CT scan, to completion of closed thoracic drainage, to the start of operation, as well as the length of stay in resuscitation room and hospital were significantly lower after the application of the Medicalsystem trauma system. The mortality was decreased by 8.6% in the after system group compared with that in the before system group, but there was no statistical difference.Conclusion:The Medicalsystem trauma system can optimize diagnosis and treatment process for trauma patients, and accordingly improve the treatment efficiency and shorten the treatment time. Therefore, the Medicalsystem trauma system deserves further popularization and promotion.

简介：形状skeletonization(即，中间的轴抽取)在许多视觉计算应用程序是强大的例如模式识别，反对分割，登记，和动画。在这篇论文，作者扩展与距离地信息相结合到多角形的网孔基于他们的微分性质代表的任意的3D固体的近似中间的斧子的散开方程的使用。它为通常使用的3D为中间的轴抽取提供一个其他却自然的方法多角形的模型。由沿着时间轴解决PDE，这个系统不能仅仅快速提取输入网孔的基于散开的中间的斧子，而且允许用户设想抽取进程在每次走。另外，建议模型提供用户雕刻提取中间的斧子的一套操作工具箱，然后使用基于散开的技术根据原来的输入数据集恢复相应使变形的形状。这基于骨骼的形状操作为复杂网孔对象的动画和变丑提供一个快、容易的方法。
