However, for the level of precision [Scott] wanted ... Most of us already have a 3D scanner in our pocket in the form of a smartphone, which can be used for photogrammetry.
The conversion to a 3D scanner meant adding another axis, and to do this with sufficient precision required flipping the rig on its side, salvaging the fantastic bearings from a VHS machine ...
The team developed a model that fed the 3D surface scans into a dual-energy X-ray absorptiometry, or DXA scanner. With the inputs, the DXA scanner measured quantities of muscle, fat and bone. The DXA ...
