Generation of Missing Medical Slices Using Morphing Technology

To estimate the locations and intensities of pixels that would appear in the nonexistent int,ermediate slices. This paper presents a new method for generation of the missing medical slices from give two slices. It uses the contours of organs as the control paramet,ers to the intensity information in t,he physical gaps of serial medical slices. The snake model are used for generating the control points required for the elast,ic body spline morphing algorithm, which were previously manually specified. Cont,onr information derived from this segmentation prc-process is then further processed and used as control paramet,ers to warp the corresponding regions in both input data slices into compatible shapes. In t,his 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 into similar shapes according to contour information to provide more meaningful correspondence relationship.
