Abstract
An implant containing a structurally encoded region, the implant comprising an implant body defining adjacent first and second encoded regions, the first encoded region comprising a first series of shaped inclusions in a first pattern of relatively differing opacity figures, and the second encoded region comprising a second series of shaped inclusions in a second pattern of relatively differing opacity figures, the first and second encoded regions being disposed such that, when the first encoded region and second encoded regions are viewed by reading illumination from a position wherein the first pattern and second pattern overlap, a third pattern is revealed by the reading illumination, the third pattern being different than the first and second patterns, and comprising shape or surface characteristics representing structurally encoded data. The invention further comprises systems and methods of manufacturing, using and reading the same.
