摘 要：As the role of medical imaging in clinical diagnoses and treatment has been more and more important,CT scan has been applied more widely.How to extract abdominal artery from CT image automatically and accurately has a significant value for abdominal artery disease.Because the medical image is of complexity and diversity,traditional segmentation method cannot complete the segmentation task very well.Therefore,this paper presents a method for extracting abdominal artery from CT images using three-dimensional region growing algorithm combined with image morphology.The experimental results show that the proposed method is an effective way for improving the accuracy of abdominal artery segmentation.
