1. A method for automatic segmentation, comprising: selecting a deformable model of an anatomical structure of interest imaged in a volumetric image, the deformable model formed of a plurality of polygons including vertices and edges;displaying the deformable model on a display;detecting a plurality of feature points of the anatomical structure of interest, each of the plurality of feature points corresponding to each of the plurality of polygons; andadapting the deformable model by moving each of the polygons toward the corresponding feature point by moving the vertices of each polygon toward a boundary of the anatomical structure of interest, forming a segmentation of the anatomical structure of interest;wherein at least a portion of the anatomical structure of interest is a normally symmetrical structure, and the method includes: determining deviations from a mean vertex value relative to a mid-sagittal plane of the normally symmetrical structure to determine abnormality, anddisplaying the deviations to show a deformation in the normally symmetrical structure. 2. The method of claim 1, wherein the deformable model is selected from a database of structures stored in a memory. 3. The method of claim 1, wherein the feature points lie substantially along the boundary of the anatomical structure of interest. 4. The method of claim 1, further comprising receiving a user input via a graphical user interface, the user input selecting an option in regard to segmentation. 5. The method of claim 4, further comprising generating a response to the user input. 6. The method of claim 4, wherein the user input includes selection of one of: calculating a volume of the segmentation and determining a curvature at a selected point. 7. The method of claim 1, wherein the anatomical structure of interest is a brain region. 8. The method of claim 1, wherein different deviations are displayed in different colors. 9. A system, comprising: a processor selecting a deformable model of an anatomical structure of interest imaged in a volumetric image, the deformable model formed of a plurality of polygons including vertices and edges; anda display displaying the deformable model,wherein the processor: detects a plurality of feature points of the anatomical structure of interest, each of the plurality of feature points corresponding to each of the plurality of polygons,deforms the deformable model by moving each of the polygons toward the corresponding feature point by moving the vertices of each polygon toward a boundary of the anatomical structure of interest, forming a segmentation of the anatomical structure of interest,wherein at least a portion of the anatomical structure of interest is a normally symmetrical structure, and the processor: determines deviations from a mean vertex value relative to a mid-sagittal plane of the normally symmetrical structure to determine abnormalitythe deviations to show a deformation in the normally symmetrical structure. 10. The system of claim 9, further comprising: a memory storing a database of structures from which the deformable model is selected. 11. The system of claim 9, wherein the feature points lie substantially along the boundary of the anatomical structure of interest. 12. The system of claim 9, further comprising: a graphical user interface receiving a user input selecting an option in regard to segmentation. 13. The system of claim 12, wherein the processor generates a response to the user input. 14. The system of claim 12, wherein the user input includes selection of one of: calculating a volume of the segmentation and determining a curvature at a selected point. 15. The system of claim 9, wherein the anatomical structure of interest is a brain region. 16. The system of claim 9, wherein the display displays different deviations in different colors. 17. A non-transient computer-readable storage medium including a set of instructions executable by a processor that cause the processor to: select a deformable model of an anatomical structure of interest imaged in a volumetric image, the deformable model formed of a plurality of polygons including vertices and edges;display the deformable member on a display;detect a feature point of the anatomical structure of interest corresponding to each of the plurality of polygons; andadapt the deformable model by moving each of the polygons toward the corresponding feature point by moving the vertices of each polygon toward a boundary of the anatomical structure of interest, forming a segmentation of the anatomical structure of interest;wherein at least a portion of the anatomical structure of interest is a normally symmetrical structure, and the instructions cause the processor to: determine deviations from a mean vertex value relative to a mid-sagittal plane of the normally symmetrical structure to determine abnormality,the deviations to show a deformation in the normally symmetrical structure. 18. The medium of claim 17, wherein the anatomical structure of interest is a brain region. 19. The medium of claim 17, wherein different deviations are displayed in different colors. 20. The medium of claim 17, wherein the deformable model is selected from a database of structures stored in a memory.
