To estimate the locations and intensities of pixels that would appear in the nonexistent intermediate slices. In this paper, we propose an interpolation method that uses the contours of organs as the control parameters to the intensity information in the physical gaps of serial medical slices. The snake model are used for generating the control points required for the elastic body spline morphing algorithm, which were previously manually specified. Contour information derived from this segmentation pre-process is then further processed and used as control parameters to warp the corresponding regions in both input data slices into compatible shapes. In this way, the intensity information for the interpolated intermediate slices can be derived more faithfully. In comparison with the existing intensity interpolation methods, like linear interpolation, which only consider corresponding points in a small physical neighborhood, this method warps the data images minto similar shapes according to contour information to provide more meaningful correspondence relationship.
