In order to achieve the hierarchical visualization of the human spine and blood vessels by using the CTA data,the recognition of the typical organization can be realized by properly vtilizing the intensity distribution of different organizations.By tacking the key problem of organization gray level overlapping,the separation of important organizations blood vessels and bone can be realized by three-dimensional region growing algorithm based on confidence-connected.Finally,the three-dimensional reconstruction is performed by volume rendering.The hierarchical visualization of the abdominal skin,muscle,bone and blood vessels is realized,and the structure can be displayed separately,can be freely rotated and zoomed in and out.By adjusting the parameters and three-dimensional segmentation, hierarchical visualization can be easily achieved.So it can provide a more clear and intuitive three-dimensional model for the doctor.
