Abstract
How to quickly obtain the precise local region images of main structure within the skull from the whole set of computed tomography (CT) image is a significant job as well as a difficult task when analyzing the skull CT images. A local segmentation method of skull CT image based on morphological processing and sparse field level set is presented in this paper. First, using various morphological operations to remove the unnecessary regions and get the rough local image of target region. Then taking its contour as the initial evolution curve and utilizing the sparse field level set method to segment the skull CT image, the precise local region of main structures within the skull can be obtained, such as occipital bone which is prone to injury. Moreover, the target contour obtained by the previous segmentation can be used as the initial contour of the next image segmentation, because the adjacent slices image of CT are very similar. It helps to segment the whole set of CT image more quickly which is conducive to save a lot of time in clinical diagnosis. The experiment results show that the proposed method is feasible and has a great effect.
