基于MRI的开颅手术仿真系统设计
Design of Craniofacial Surgery Simulation System Based on MRI
摘要
Abstract
Traditional clinical medical visualization tools can neither simulate the practical problems during surgical procedure, nor obtain the view after surgery to evaluate the impact on the crucial organization. The craniotomy simulation system is proposed in this paper to solve this problem. Comparing with traditional medical visualization tools, it analyses and segments the crucial tissues prior to reconstruction, and makes the rendered scene more real. In particular, it is designed as loose coupling, which benefits the following functional development in the future. Based on MRI data, it segments the crucial organization region automatically and sets up a mixture surgery model of multiple anatomical structures, which supports window regional planning, surgical approach, and the virtual cutting process. It applies cutting implicit function to multiple anatomical structure models, to provide critical areas’ scene of the cerebral cortex and superficial veins. Implementation results show that it allows doctors to validate different surgical options and evaluate the pros and cons. It has great significance on reducing the risk of surgery, training surgery procedure and improving the surgical accuracy.关键词
