Medical Imaging methods such as Computerized Tomography (CT) have come to play an inevitably important role in non-invasive diagnostic performance for physicians. In 1988, W. -C. Lin, C. -C. Liang, and C. -T. Chen published a paper in IEEE Trans, on Med. Imaging, vol. 7 on "Dynamic Elastic Interpolation for 3-D Medical Image Reconstruction from Serial Cross Sections." Their mathematical approach takes too much computational time. This paper employs a much more mathematically direct and elegant approach, and therefore reduces computational time to about a tenth of that proposed by Lin et al. Apart from the savings in computational time, performance is also shown in the capability to create better approximation of the goal contours while performing all the intercontour interpolations exemplified by Lin et al.
