Abstract: Analysis on the accurate segmentation and 3D reconstruction of brain tumors are important for the diagnosis of brain tumor diseases. This paper presents an automatic segmentation method for brain tumors. According to the symmetry of human brain structure information, a rough segmentation of brain tumor can firstly be realized by region growing method, and then taken as the initial level set contour for the further accurate segmentation by means of geodesic active contour (GAC) model. Experimental analysis shows that the model has good weak-edge ability on segmenting uneven gray scale. Finally, surface rendering, reconstruction and visualization of the segmented brain tumor sequence images are carried out to provide more dimensional information for brain tumor research.

Key words: geodesic active contour (GAC) model, surface rendering, brain tumor, region growing method
