摘要
Abstract
A method which using double-snake model segmentation algorithm to determine internal and external borders of the skull in the CT images was proposed,using polygon to approach its borders ,then by calculating the distance between the line segments of inner and outer polygons to get the data of the thickness of pre-frontal ,parietal and occipital bones in image.So it can provide a good method to the application of getting thickness information of skull base on CT image. Following an analysis of the thickness data of pre-frontal ,parietal and occipital bones at different positions ,the standard deviation and the rate of change of the thickness of parietal and occipital bones were proved to be larger. The proposed method can describe the boundary of the skull accurately,this method will provide a basis to establish a database of human heads and research the biomechanics modeling of head and so on.关键词
