摘要
颅骨是人体中最重要的组成部分之一,起着保护和支撑脑部组织的作用。现实中由于种种原因,许多人承受着颅骨缺损的痛苦,不仅影响外观,而且还可能导致脑组织损坏。如何有效地修复缺损的颅骨成了国际研究的热点。目前,医生主要是通过观察病人的CT影像确诊病人颅骨损坏情况,并通过手工制作修复体,这极大地依赖于医生的技术和经验。为了解决这一问题,本文利用交互技术——B样条曲线对CT数据中的某些具有代表性的层或逐层修复缺损的颅骨,使颅骨修复过程更加方便有效,最终产生出数字修复体,并存储为特定的格式,利用基于计算机辅助设计和制造技术的数控机械生产出合适的修复体。该方法能够缩短手术时间,减少手术风险,并能够设计出更符合病人的颅骨修复体。
Skull bone is one of the most important parts in the human＇s body,which protects and supports the brain tissues. Nowadays,due to many various reasons,a lot of people suffer from the skull bone defects,which not only affect the appearance,but also may cause brain damages. How to repair the skull bones for people effectively has become an international hot topic. At present,doctors diagnose the state of the bone defect illness mainly depending on observing the CT images of patients,and make the repair model by hand. It mainly depends on the technique and experience of the doctors. In order to solve this problem,this paper focuses on using the interactive technology to make the skull repair procedure efficient. During this process,we used B-Spline to repair some typical slices or each slice of the CT images,construct the restoration that fits the skull surface and then transfer it as a file in specific format to a machine based on technology of computer aided design and computer aided manufacture to produce a real restoration. This method can shorten the time of operation,reduce the risk of operation,and produce a suitable repair result for patients.
