1. A system for periodic body scan differencing for detecting changes in surface and subsurface body scans over time comprising a scanner configured to project a light pattern comprising a plurality of different colored points not forming colored lines onto a body at a first point in time; capture two images offset in distance from one another from two cameras at said first point in time; create a first scan having a first three-dimensional shape for said body at said first point in time through triangulation to a particular colored point in said plurality of different colored points in each of said two images; project said light pattern comprising said plurality of different colored points not forming colored lines onto said body at a second point in time; capture two images offset in distance from one another from two cameras at said second point in time; create a second scan having a second three-dimensional shape for said body at said second point in time through triangulation to said particular colored point in said plurality of different colored points in each of said two images; a computer configured to morph said first scan and said second scan to minimize differences; difference said first scan and said second scan; detect a morphological acceleration rate of change over time for said second scan relative to said first scan; highlight differences between acceleration rates of change for each of said first scan and said second scan using colors other than the scanned color to indicate changes between said first scan and said second scan in an atlas view; and, produce a morphological difference image from said differences and display said morphological difference image in said atlas view.
