中文摘要 | 颅缝早闭是婴幼儿常见疾病,发病率约为两千分之一,患者通常表现为颅面畸形,严重影响其外貌和脑部正常发育。目前通常采用颅骨重塑外科手术对颅骨进行切割和拼接以达到扩容和美观的目的,而外科医师凭手术经验和主观判断制定手术方案,随意性大,主观性强,难以保证最佳的手术效果。因此,该手术对医生的临床经验和操作水平都提出了很大的挑战,国内只有小儿神外顶级医院才具备高质量手术的能力,导致只有极少数患者能够接受治疗。为提高手术实施效率,特别是降低手术门槛,需要进行颅骨重塑手术术式的智能化、定量化和标准化研究。其中,如何学习并利用资深医生的手术方案和设计经验来标准化颅缝早闭手术流程,以及如何定量评估手术效果,是亟待解决的技术难题。本文以常见的矢状缝早闭和冠状缝早闭为对象,研究基于模板匹配的颅缝早闭手术切割方案规划方法,完成的主要工作如下: |
英文摘要 | Craniosynostosis is a common disease among infants and young children, there are about one in two thousand infants suffered from it. Patients usually present with craniofacial deformities, which seriously affects their appearance and normal brain development. Nowadays, surgery is usually taken to cut and splice the skull on the purpose of expanding and bringing the skull back to normal. However, doctors conduct operations mainly based on their experience and subjective judgment, which is arbitrary, subjective and no guarantee to the best postoperative results. Therefore, it poses a great challenge to the clinical experience and operation level of the doctors. In China, only the top pediatric hospitals have the ability to perform high-quality surgery, causing only a few infants have chance to be treated. In order to improve the efficiency of surgical operations, especially to reduce the difficulty of the surgery, it is necessary to conduct intelligent, quantitative and standardized research on the operation method for craniosynostosis. Therefore, the urgent technical problem to be solved is how to extract and learn the surgical experience of senior doctors' to standardize the surgical plan procedure for craniosynostosis and how to evaluate the postoperative effect quantitatively. This thesis focus on the sagittal suture closure and coronary suture closure, and proposed a surgery planning method based on template matching for craniosynostosis. The main tasks completed are as follows: |
