Abstract
A method, system and apparatus determines an individual body composition by the summation of regional estimates determined from anatomical subregion geometry (e.g., lengths, surface areas, volumes). The anatomical subregion geometry may be based on a surface mesh presented by a 3D whole-body scanner. Regional composition estimates are produced by processing subregion geometry combinations by fitted weight values. The regional composition estimates are then summed to produce an individual body composition.
Claims20
A system, comprising:
- a three-dimensional (3D) body scanner;
- and
- a regional body composition estimator, coupled to the 3D body scanner, having a processor configured to:
- generate one or more anatomical subregion geometries based, at least in part, on a surface mesh received from the 3D body scanner,
- produce regional composition estimates by processing the subregion geometries by weights, and
- produce an individual body composition from the regional composition estimates.
A regional body composition estimator apparatus, comprising:
- regional body composition estimator having:
- a memory;
- and
- a processor, coupled to the memory, configured to:
- receive one or more anatomical subregion geometries and associated regional body compartment mass values from the memory,
- fit a predictive model to the regional body compartment mass values using combinations of subregion groupings as inputs, and
- determine the combination of subregion groupings having a best fit.
A method, comprising:
- receiving one or more anatomical subregion geometries and associated regional body compartment mass values;
- iteratively fitting a predictive model to the regional body compartment mass values using combinations of subregion groupings as inputs;
- and
- determining the combination of subregion groupings having a best fit.
A method, comprising:
- generating one or more anatomical subregion geometries based, at least in part, on a surface mesh;
- producing regional composition estimates by processing the subregion geometries by weights;
- and
- producing an individual body composition from the regional composition estimates.
