An Implementation of Piecewise-Linear Interpolation for 3D Slice Reconstruction

In the world of medical computing, 3D reconstruction of slice data is a common topic. A slice is a single cross-section image obtained by CT or MRI devices, and can be processed to obtain polygonal data describing the material to be analyzed. For example, if images are taken of a heart, contours around the cross sections might be found and saved as point data for further processing. An example of this is shown in Figure 1. It is then possible to reconstruct these polygonal contours into a 3D object by connecting the appropriate pieces together.
