基于CT扫描数据估计去骨瓣减压术后头皮表面积 田谦益1,2 朱剑萍3 刘兆田1 李敬敬1 高莲1 张金鹏3 施心陵1 赵宁辉3* (1. 云南大学信息学院电子工程系，昆明，650091;2.363000，闽南师范大学信息学院，漳州;3.昆明医科大学第二附属医院，神经外科，昆明，650118) 摘要 目的：根据CT扫描颅骨和头皮层数据，提出一种估计去骨瓣减压术后颅脑缺损区头皮表面积的方法。 方法:首先，通过Mimics软件从颅脑CT扫描头骨及头皮层数据分别建立相应的颅骨和头皮颅脑三维几何模型；然后，分别从对应模型中估计去骨瓣减压术后缺损区域相应的头皮表面积；最后，为验证上述方法的有效性，本文将选定病例的Mimics估计结果与从二次曲面系统辨识模型获得的计算结果进行对比。 结果：头骨及头皮颅脑三维几何模型估计结果均与系统辨识模型的计算结果一致，但头皮颅脑三维几何模型估计结果与系统辨识模型计算值的接近程度更高。 结论：用本文提出的方法进行去骨瓣减压术后头皮表面积的估计对后期在颅骨修补术中皮瓣评估的研究和转化应用中更具有指导意义。 关键词：CT扫描；头皮层；去骨瓣；二次曲面；系统辨识；头皮表面积 Estimated the surface area of the scalp after craniectomy based on CT scan of the skull and the scalp data (1 Department of Electronic Engineering, School of Information, Yunnan University, Kunming, 650091 2 ?College of?Computer?Science, Minnan Normal University, Zhangzhou, 363000 3 Department of Neurosurgery, the Second Affiliated Hospital, Kunming Medical University, Kunming, 650118) Abstract Objective: According to the datas the skull of CT scan and the scalp,an method is made to estimate the surface area after craniectomy of the defect scalp. Method: First, to establish the three-dimensional geometric model of the scalp from the brain CT scan of the skull and the scalp data respectively through Mimics software; then, to estimate the defect area after decompressive craniectomy of the correspondingthe defect area; Finally, in order to verify the effectiveness of the above methods, we selecte the results of the cases through Mimics compared with the results obtained from the quadric system identification model. Conclusion: The proposed method used after decompressive craniectomy estimated surface area of the scalp is more instructive to clinical diagnosis between the latter part of the skull flap repair and conversion application assessment study Key word：CT scan;the scalp;craniectomy;quadric; system identification; the surface area of scalp 近年，去骨瓣减压术常用于缓解各种病因导致的颅内高压，引起去骨瓣区域皮瓣发生相应的生理及病理变化，直接表现为头皮表面积的改变，这种改变可能是颅骨修补术后并发症发生的潜在因素。为此，本文提出一种从CT扫描颅骨及头皮层数据估计去骨瓣减压术后头皮表面积的方法。
