SYSTEM FOR RAPID AND ACCURATE QUANTITATIVE ASSESSMENT OF TRAUMATIC BRAIN INJURY
First Claim
1. A method for automatic segmentation, comprising:
- selecting (210) 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 (220) the deformable model on a display (106);
detecting (240) a feature point of the anatomical structure of interest corresponding to each of the plurality of polygons; and
adapting (250) the deformable model by moving each of the vertices toward the corresponding feature points until the deformable model morphs to a boundary of the anatomical structure of interest, forming a segmentation of the anatomical structure of interest.

Abstract
A system and method for automatic segmentation, performed by 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 feature point of the anatomical structure of interest corresponding to each of the plurality of polygons and adapting the deformable model by moving each of the vertices toward the corresponding feature points until the deformable model morphs to a boundary of the anatomical structure of interest, forming a segmentation of the anatomical structure of interest.

11. A system, comprising:
-
a processor (102) 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; and a display (106) displaying the deformable model, wherein the processor (102) further detects a feature point of the anatomical structure of interest corresponding to each of the plurality of polygons to deform the deformable model by moving each of the vertices toward the corresponding feature points until the deformable model morphs to a boundary of the anatomical structure of interest, forming a segmentation of the anatomical structure of interest. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A computer-readable storage medium (108) including a set of instructions executable by a processor (102), the set of instructions operable to:
-
select (210) 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 (220) the deformable member on a display (106); detect (240) a feature point of the anatomical structure of interest corresponding to each of the plurality of polygons; and adapt (250) the deformable model by moving each of the vertices toward the corresponding feature points until the deformable model morphs to a boundary the anatomical structure of interest, forming a segmentation of the anatomical structure of interest.
