AnSur Software

In order to quantify the changes in contour measured by the profiler, it was necessary to develop software that would present the digitized data as a three-dimensional surface. Dr. Ralph DeLong developed the software program AnSur© (Regents, University of Minnesota), which provides full three-dimensional fitting of two surfaces with the necessary graphics to locate and analyze changes that occur between the two surfaces, in terms of volume (mm³) and depth (µm).
