Abstract
System and method of generating a warp field to generate a deformed image. The system and method use segmentation in a new method of image deformation with the intent of improving the anatomical significance of the results. Instead of allowing each image voxel to move in any direction, only a few anatomical motions are permissible. The planning image and the daily image are both segmented automatically. These segmentations are then analyzed to define the values of the few anatomical parameters that govern the allowable motions. Given these model parameters, a deformation or warp field is generated directly without iteration. The warp field is applied to the planning image or the daily image to deform the image. The deformed image can be displayed to a user.
